PCB assembly has to be completed according to set specifications and these instructions must be followed to the letter to complete quality work within the time constraints set by the client. Our team at MJS Designs has decades of experience working in the USA on PCB assembly work, and in our latest post we’re highlighting the process for PCB assembly.

SMT and Through-Hole

In taking on the PCB assembly process, teams will only use both SMT and through-hole forms of assembly. SMT (Surface Mount Technology) involves the mounting of electronics on the surface of a printed circuit board. One of the smallest within the industry is the 01005 assembly, which features components measuring 0.2mm to 0.4mm. Through hole processes involve the use of pre-drilled holes on PCBs to ensure optimal placement and alignment of leads on the components. Some companies still take on this work by hand, but many now rely on automated insertion machines to ensure reliability within the working process.

Checking for Flaws

It’s often critical to check PCBs for surface flaws to mitigate performance and functionality challenges later in the development process. Flaws that can be picked up via scanning include inconsistent soldering and out-of-place or missing components. These flaws can then be resolved by maintenance teams to ensure the board meets the performance standards required.

Lead Processes Used to Enhance Performance

Another mechanism for improving the performance of the PCB system is the use of lead components. Lead processes such as QFN (Quad Flat No Leads) and uBGA help reduce self-inductance as well as resistant levels within the PCB. They also offer less impedance discontinuity than other systems.
