PCBs are an integral component of any electronic device be it a small toy or a sophisticated computer. Its complex interconnected components comprising of resistors, diodes, capacitors and more allow the device to work in tandem. In a sense it is like the “brain” of the system”. In high reliability systems particularly — such as oilrigs, space satellites and others failures can have devastating consequences. It is critical, therefore the PCB Assembly process is flawless and common mistakes in the assembly are watched out for.
To be able to create high quality PCBs, the one thing that needs to be in order is the supply chain. It is important to check their availability, quality as well as price. Consistent ability to source the components is critical towards managing the manufacturing cycle of the product. You also need to be doubly sure of the quality of the products. Counterfeit components can have disastrous consequences on the product performance and your reputation. It is also important to check the lead-time of components especially as the volumes required increase. While you may take initial samples directly from manufacturers, remember to budget for lead times as volumes go up.
A common problem faced at the manufacturing stage is the nuances in PCB layout. While several designs may look good on paper, manufacturing them may be a different ball game. For example if the design has a large number of components positioned closely together, soldering them may be an issue. In case of a double-sided PCB, you need to make sure that the largest components are placed on one side. Essentially you need to make sure that the pcb layout is indeed viable at the manufacturing stage. If for example, holding down complicated parts requires them to be glued manually, it will add to your assembly time as also leave margins of error.
A common problem associated with PCB Assembly, is that the testing is often done after the manufacturing. What needs to be done, however, is to design the test points as you conceive the design. There are in fact a whole lot of PCB Functional testing ensure that the PCB is functioning correctly.
A whole lot of PCB Challenges also emanate from the fact that increasingly components are shrinking in size and circuits are becoming more and more sophisticated. Therefore, all the more chances of defects in the assembly.
PCB Assembly therefore requires an effective root cause analysis to ensure that corrective action is taken so that the problem does not recur. In addition a detailed failure analysis ensures ways to improve the product as also to correct faults that may not have been noticed at the design stage.
