Circuit board production need to pay attention to what

manufacturing

PCB circuit boards are widely used in electronic products, instruments, electronic computers and other electronic devices, and are a very important basic assembly component in electronic devices. Therefore, in the case of PCB circuit board production, only the various areas are considered clearly, in order to ensure that the application of electronic equipment is not prone to encounter problems.2 oz copper thickness in mm So, what do you need to pay attention to when making PCB circuit boards?

1, the type of manufacturing

PCB circuit boards are divided into single-sided, double-sided and multilayer boards. Single-sided aluminum substrate conductive pattern is very simple, only one side of the substrate has a conductive pattern, while the double-sided board has a conductive pattern on both sides. Usually, metallic material holes are used to connect the double-sided conductive images. Multilayer PCB circuit board substrates have many layers and complex conductive types, which are more suitable for high-precision and complex electronic devices. Therefore, quality-assured PCB circuit board manufacturers should consider which PCB circuit board must be used in production.

2, the raw material of the substrate

Polyimide film consists of polymer materials, resin materials and modified raw materials, which can be used as the base material of the copper-clad board. There are many types of resin materials, such as urea-formaldehyde resin, epoxy resin adhesive, PTFE and so on. There are two improved raw materials, cardboard and fabric surface, which determine the physical properties of the substrate, such as cold resistance and tensile strength. Therefore, in the production of PCB circuit boards, the substrate should be used in what kind of raw materials is also important to note.

3, the non-electrical properties of the copper-clad laminate indicators

The quality of the copper-clad plate will directly damage the quality of the PCB circuit board,plated through hole vs via and the quality of the copper-clad plate is mainly reflected in the peel strength, compressive strength, expansion and contraction, tensile strength, resistance to immersion welding and other non-electrical performance indicators, therefore, the production of PCB circuit boards should be considered in the production of non-electrical performance indicators of the copper-clad plate.

Since PCB circuit boards are the basic components of electronic equipment, it is necessary to use high-quality PCB circuit boards. Therefore, customers should not only look for good after-sales maintenance service circuit board manufacturers to produce PCB, but also in the case of PCB circuit board production to consider all aspects of the PCB, try to make the PCB design program to meet the application requirements.
