The PCB fabrication specifications and manufacturing data form the basis of the PCB assembly process. While a poorly designed PCB may hinder the processing and potentially lower the quality of the final PCB assembly product, a well-designed PCB will make subsequent PCB assembly processing easier. What aspects of PCB design will therefore influence PCB assembly procedures? The following are some typical problems for which circuit board designers require an attenuation.

The top five mistakes that you should look out for in PCB assembly.

Flex-Cracking

On the technical side, flex-cracking refers to excessive bending of the PCB under a ceramic chip capacitor. The ceramic chip capacitor cannot withstand excessive stress due to its brittle nature.

Failure to Adequately Gauge the Performance Environment

One of the most common mistake made by PCB designers is failing to cater for the environment in which the board will operate during the design stage.

Inadequate Communications

PCB assembly will often involve a number of participants. There is the designers, the fabricators and the Electronic Manufacturing Services (EMS) provider.

Lack of Design Reviews

For companies that do not have well defined rules on the flow of work from initial product assembly specification, through design to delivery of the final product, there may be problems in design reviews.

Lack of Design Back-ups

A very common mistake in any type of design work is failing to back-up the copies of your work.

To do this, it is essential to understand the typical design faults that lead to incorrect PCB assembly. Board assembly mistakes include overlapping components, pad lifting, and solder bridges are caused by inadequate clearances, incomplete design data, incorrect component positioning, and poor heat management.

Electromagnetic compatibility, trace planning, component selection, layout, and PCB design are all crucial components. By following these pointers, you can enhance product performance and reliability by avoiding typical design blunders. Future PCB design should focus more on these elements and raise the caliber and effectiveness of circuit design.
