Wave soldering plays a decisive role in fixing components on Printed Circuit Board during PCB Assembly process. As manufacturing technology gradually goes upgrading and people's environmental protection awareness takes off, wave soldering is further classified into lead wave soldering and lead-free wave soldering.
Introduction: A Printed Circuit Board (PCB) is the base for wiring and supporting surface-mounted, socketed components in electronics. In circuits where there is a need for find conductive traces (such as computer systems), these PCBs are made through the photolithographic process.
Documenting your entire design process may seem tedious or inconvenient at times, but it ends up being a critical piece of creating a great product. PCB design is no exception, so designers need to be aware of documenting the right information, in the right way, to successfully manufacture their final product.
Various requirements for printed circuit boards make the use of different circuit board substrates necessary. Whereas for many standard applications the classical FR4 material is sufficient, possibly in high Tg version (for improved thermo-mechanical properties), for other areas (such as high frequencies) alternate materials are absolutely required.
A good working relationship between the customer and PCB supplier is vital to the success of any project. Costly design errors and delays in manufacturing can be prevented by discussing details in advance. Communication is key to avoiding PCB file errors.
Through-hole technology (tht), also spelled "thru-hole", refers to the mounting scheme used for electronic components that involves the use of leads on the components that are inserted into holes drilled in printed circuit boards (PCB) and soldered to pads on the opposite side either by manual assembly (hand placement) or by the use of automated insertion mount machines.
Select the correct grid - set and always use the grid spacing that matches the most components. While multigrids seem to be a significant utility, engineers can avoid the pitfalls of spacing setups and maximize board use if they can think much more early in the PCB layout design.
The PCBs of yesterday were mainly rigid. In this contemporary era of mobile technologies where everybody is inching toward miniaturization, a will need was felt for circuit boards that were lightweight, flexible, thin, compact, and had high wiring density. Flexible printed circuit boards were invented to answer these requirements.
During the inspection process you notice that some passive components aren’t sitting quite right. It seems as though they have pivoted up to stand at attention on one of the two pads that they should be connected to. Unfortunately, a test of the circuit will result in an open.
