When it comes to PCB Manufacturing, particularly multilayer PCB manufacturing, the technology that is currently in place, is in many respects not too efficient. Not only is it time consuming, the biggest issue is that it is not foolproof when it comes to avoiding errors.

The big relief has come in the form of additive manufacturing, where it has become far easier to create complex, multilayer PCBs. This technology allows for creating high-density boards which work well especially given the current trend of miniaturization of electronic products.

Before we look at additive manufacturing in some detail, it will be worthwhile to look at some of the issues being faced when it comes to manufacturing multilayer PCBs via the traditional methods.

Issues plaguing the traditional multilayer circuit board manufacturing methods:

Time Consuming

First up, the traditional method is time-consuming. This is largely on account of the fact that there isn’t any significant automation. For an industry where turnaround times are a critical source of competitive advantage, no marks for guessing, that this comes with its own set of problems. Especially, if you are dealing with high-density PCBs, the time taken for PCB fabrication, as also its cost shows a substantial increase.

Material Wastage

Traditional PCB fabrication also comes with a significant amount of wastage of material. From a cost standpoint also this results in less than optimal costs.

Use of hazardous material

At a time where stopping environmental degradation is the need of the hour, traditional PCB Fabrication processes use a whole lot of hazardous chemicals that cause significant environmental damage.

What additive manufacturing effectively does, is to mitigate each of the above risks and offer tangible benefits through 3D printing.

Additive manufacturing process for multilayer PCB manufacturing –

An additive manufacturing process that employs 3D printing of PCBs, essentially uses a layer-by-layer printing process to produce multilayer PCBs.

We do have additive manufacturing processes that involve printing from silver or copper nanoparticle inks directly to a FR4 substrate. However, this helps in single layer boards where the subtractive etching process is eliminated. When applied to multilayer circuit boards, there is hardly any time or cost saving as compared to the traditional PCB manufacturing process.

What works well when it comes to multilayer PCBs is the process of 3D printing. All you need are superior inkjet printing systems whereby you can opt for a layer-by-layer deposition process. What is of importance here, is that the insulating substrate can also be printed simultaneously. All you then require by way of PCB Assembly, is to add the surface finishing and PCB component placement. You do not have to undergo the drilling process since you are able to print the substrate with mounting holes.

If you look at this multilayer PCB closely, what it really has are traces and vias in a single dielectric layer. The advantage clearly lies in the fact that you do not undergo the geometric constraints that come in traditional multilayer PCB production.

Little surprise then that additive manufacturing is increasingly being used in both, complex PCB fabrication, as well as in creating multilayer PCB prototypes where speed as well as efficiency, is key. The importance of additive manufacturing is also growing on account of the fact that the need for complex, multilayer PCBs is on the increase.

Not only does it work well from the standpoint of quality, from a business perspective too it has a number of advantages, including but not limited to:

  • Reduced time of production
  • Less material wastage
  • Optimal Costs

That it can cater to low-volume, high-complexity multilayer circuit boards, is an added perk! Additionally, with the reduced time of production, the circuit board prototypes can be immediately tested. This by itself offers a number of benefits. Firstly, your time-to-market can be significantly improved and you can gain a competitive edge. If you are a startup and need a minimum viable product to showcase to investors, once again, the importance of this cannot be overstated.

Little surprise then that a lot of industries are benefitting from this new method of multilayer PCB manufacturing. With the fast turnaround enabled by additive manufacturing and engineering changes being easily accommodated, the importance of 3D printing is only slated to grow when it comes to its use by PCB Manufacturers in USA.

Improvements in the electronics industry are being increasingly led by technological advancements in Printed Circuit Boards. Whether it is providing solutions that are transforming our homes and workplaces or providing miniaturized products that add to the ease of use, the impact is far-reaching.

While the macro trends in the electronics industry have been led by developments such as Internet of Things, small home technology and more, there are a whole lot of other design aspects that electronics engineers also need to focus on. These include areas such as lowering power consumption or dealing with thermal issues, particularly under harsh environmental conditions. With teams working on challenging PCB projects, especially in mission critical areas such as defense, mining and more, delivering a successful product is extremely important. This requires a whole new approach in PCB assembly manufacturing.

When it comes to solving any complex problems, the first thing to do is to break the issue into smaller, addressable parts. This not only takes away the overwhelm that comes with complex issues it also facilitates addressing the smaller issues with measurable metrics. The technique that best defines this approach is Finite Element Analysis, or what is popularly addressed as FEA.

Simply put, Finite Element Analysis involves modeling of systems in a virtual environment so that you can solve structural and performance issues in the real world. What FEA does, therefore, is to allow for separation of the process into smaller subsystems that allow its close evaluation. A practical application of FEA is the tracking of material changes. FEA also finds extensive application in PCB Manufacturing, especially as it helps in PCB material selection. Some of the benefits of FEA include:

  • Improvement of product performance
  • Evaluation of different designs
  • Optimization of designs and reduction in material usage

PCB Manufacturing FEA Analysis

There are a host of ways in which FEA Analysis can add value to PCB Manufacturing; be it the selection of components or performance of circuits. The use of PCB FEA Analysis, therefore, adds value at various stages of the process of building boards. Below is a detailed analysis of the various types of FEA analysis that come in handy, during the design stage:

Signal and Power Integrity Analysis

It is imperative for the PCBA to function seamlessly as per set benchmarks, to ensure reliability of the product. It is largely the Signal and Power Integrity of the board that determines this. This in turn involves ensuring of aspects such as:

  • Maximizing SNR
  • Components should have ample power
  • Noise reduction on power traces

Electromagnetic Compatibility and Integrity

EMI or noise can often be a concern with boards, especially if they have RF devices. While try and as you may, complete elimination of noise isn’t a possibility. What is possible, however, is that you achieve the best EM balance for the environment. In systems where there are multiple PCBA, achieving electromagnetic compatibility is also an important design aspect.

Thermal Analysis

Thermal analysis is a Finite Element analysis that finds wide application in PCB. Essentially, it involves evaluation of the response of the board to different thermal conditions. Whether it is heat distribution on account of the power components or environmental changes, it helps determine the use of thermal pads, vias or the overall design of a thermal management system.

Other than the above, FEA Analysis also comes in handy by component manufacturers as also by testing organizations. Some of the tools required for the same include:

PSpice

This is a preferred industry tool when it comes to evaluate signal responses. With the help of this tool, you can model a wide variety of:

  • Electronic components
  • Circuits
  • Boards and more

3D Solver Clarity

This comes in handy to offer a 3D perspective and analyze the EM parameters

Celsius Thermal Solver

It provides results that ensure there isn’t excess heat that can not only damage components but also threaten user safety.

Armed with these tools you can rest assured that the integrity of the PCB has been checked and reliability of the product is assured. The partitioning approach of Finite Element Analysis ensures that precise evaluation of the different aspects is done and standards adhered to.

PCB Technology Trends

To say that the PCB industry is highly dynamic, will be to state the obvious. The fact is that changing technology is bringing about new capabilities and functionalities as far as PCBs are concerned.

A big trend, of course is miniaturization of the PCB. This trend, in turn, is being driven by some technological developments.

Let us look at some PCB technology trends:

High Density Circuitry

The one major contributor towards PCB miniaturization is the high-density circuitry that technology has made possible. Designers now have the freedom to place components close to each other without hampering the electrical flow. That and the micro vias result in highly functional PCBs that are small and light.

IoT Devices

Another technological advancement that has impacted PCB design is Internet of Things. With wearables, smart homes and more, what is needed are highly functional PCBs in the smallest of sizes. This has seen the rise of minimalistic design. All of this is made possible with HDI PCB technology. Check out how to overcome the challenges of IoT with Smart PCB Manufacturing.

Augmented Reality

From making its foray from gaming into solving real life issues, augmented reality is now making its way into manufacturing. In fact Augmented Reality is now revolutionizing PCB manufacturing as well as design. One of the aspects it makes possible, is the ability of the PCBs to take on unconventional shapes and designs. In fact the impact of AR isn’t just limited to the design aspect alone but also impacts the production process. What AR also makes easy is the ability to oversee the entire design as also make testing easy.

3D printing

This is a major technological development that has given a big boost to PCB manufacturing. 3D printing makes PCB miniaturization a reality. In fact it offers a host of other advantages including:

  • Flexibility of design
  • Improved speed
  • Waste reduction, and more.

Other than miniaturization of PCBs, some of the other PCB industry trends are as below:

High-power boards

With solar energy applications, electric vehicles and more, there is increased demand for high-power boards. With PCBs having the option to accommodate more components such as battery packs, their ability to support such applications is far higher. They can also deal with interference issues effectively.

Flex Boards

Flex and rigid-flex boards have been growing in popularity as there are increasing number of designs where size and weight limitations are stringent. Such Flexible circuit boards also work well where the applications are high-temperature and high density.

COTS components

Another trend that is shaping the PCB industry is the use of commercial off-the-shelf components. These offer a whole lot of advantages including but not limited to:

  • High reliability and efficiency
  • Suited to mission critical systems on account of stringent standardization guidelines
  • Lower overhead costs since these are ready made and not custom in-house developed products

Green PCB Manufacturing

Like any other product, PCB manufacturing is also impacted by the need for green manufacturing to ensure clean and sustainable production. While PCBs have been using fiberglass, which is environmentally friendly, new advancements demand that this gives way to usage of material such as resin-coated copper and liquid crystal polymer.

Clearly then, the PCB industry is in the throes of major technological changes. Going forward we will witness a whole lot of innovation, not just in product design but also overall efficacy.

What is important, though, is that at a time where more and more electronics require PCBs, a tight control is kept on the supply chain. That is the only way that fake elements can be kept at bay and the PCB can deliver to the new benchmarks being set.

In order to be able to harness the true potential of PCBs, you need to engage with a board manufacturer who is well-poised to take advantage of these developments.

PCB Contract Manufacturer

That PCBs are the heart of an electronic device, on which the success or failure of the device depends, is a well-known fact. What is at the heart of the PCB, however, are components that the board is built with. While the layout or the schematics of the board has a scope to be changed, the right components can make or break the PCB. Supply chain management in the Electronics Manufacturing Industry, therefore, remains a very critical aspect. There are a whole lot of challenges that this area is faced with. Let us look at some of the top challenges in supply chain management:

Availability

The primary challenge of course is the availability of materials. In fact, most delays in PCB Manufacturing can be traced to the fact that the specific components that have been mentioned in the bill of materials may not be readily available. It is even a possibility that the requirement could have simply been copied from an older CAD, while its production has currently been discontinued. Some parts could also be out of stock and can lead to delays. It is, therefore, imperative to check the bill of materials thoroughly to see that all the parts are available much before the production process begins.

In fact components, very often, have a status column attached to them. This can offer some critical information to the engineer. For example:

  • NRND or not recommended for new designs can indicate to the engineer that for newer products these parts should not be used
  • OBS or obsolete parts again means that other options should be chosen
  • EOL or end of life once again indicates that such parts should not be used.

A fair understanding of these aspects will ensure that production is not stuck on account of unavailability of components at a later stage.

Quality Control

This of course is a non-negotiable aspect. It is important to go with component manufacturers who exercise the highest level of quality control. This is where a PCB Contract Manufacturer USA who has a relationship of trust with vendors, comes in handy. They can ensure that the PCB boards and in turn the final products are consistent as far as quality is concerned. Not only do you need to look for product quality, other aspects to watch out for include:

  • Does the vendor have a structured quality assurance program?
  • Does the packaging, shipping and handling conform to quality protocols? This includes a number of aspects including moisture control, so that the products aren’t damaged during transit
  • Do the parts meet traceability requirements?

Price

Price of components, of course, is an important aspect that determines whether or not the PCB boards will be competitive. Attention therefore needs to be paid to getting the best possible price of the component. Some of the aspects that will determine the price include:

  • Bulk orders
  • Ordering well in advance
  • Existing relationships with vendors

PCB Contract manufacturers who have years of experience in the field, will therefore be able to offer far more competitive quotes rendering the final product that much more competitive in the market.

Here is how your PCB Contract Manufacturer can help:

There are many aspects of Supply Chain Management that an experienced PCB Contract Manufacturer can help with. These include but are not limited to:

Review the design for manufacturability

  • Review the design for manufacturability
  • First things first, a PCB Contract Manufacturer can study your design from the manufacturability standpoint.
