In the PCB manufacturing process at circuit board factories, reserving process edges is crucial for subsequent SMT chip processing. The process edge assists in producing the plug-in board, which involves the wave soldering on two or four sides of the PCB. It primarily aids in production, is not part of the final PCB, and can be removed after manufacturing.
Since process edges consume additional PCB material and increase overall costs, it is essential to balance economic efficiency and operability when designing the PCB process edges. For uniquely shaped PCBs, original designs featuring two or four process edges can be significantly simplified using a splicing method. When creating the splicing method for SMT processing, it is important to consider the track width of the SMT placement machine. For splicing boards wider than 350mm, communication with the SMT supplier’s process engineer is necessary.
The primary purpose of the process edge is to enable the SMT placement machine to securely grip the PCB during operation. If components are positioned too close to the track edge, they may be inadvertently picked up by the SMT nozzle, leading to collisions during placement and halting production. Therefore, it is essential to reserve a process edge of about 2-5mm. This precaution also applies to plug-in components to prevent similar issues during wave soldering.
Additionally, the flatness of the PCB process edge is critical in PCB production. When removing the process edges, it is vital to ensure they are flat, especially for PCBs that require high assembly precision. Any uneven burrs can misalign mounting holes and create significant challenges during subsequent assembly.
