printed circuit

Printed circuit board components are the core concept of DFM

Circuit designers and technicians of products must master and follow PCBA manufacturability design procedures. Following PCBA manufacturability design procedure is the first prerequisite for product manufacturability design.

PCB(printed circuit board) manufacturing process and process details

To summarize, the production process of a typical pcb factory is as follows: blanking → inner fabrication → pressing → drilling → copper plating → outer fabrication → soldering paint printing → text printing → surface treatment → contour processing.

Printed circuit boards and lead-free assembly requirements

Why is lead not allowed on printed boards, assembly processes and products? There are two reasons for this: first, lead is toxic and affects the environment; Second, leaded solder is not suitable for new assembly technology.

Reverse deformation mounting of printed circuit board components

During the installation of the reinforced frame and the PCBA, and the installation of the PCBA and the chassis, directly or forcibly install the warped PCBA or the warped reinforced frame and install the PCBA in the deformed chassis.

printed circuit board wiring

Key signals such as analog small signal, high-speed signal, clock signal and synchronization signal are routed first, and the devices with the most complex connection relationship on the board are routed first.

Recycling of waste printed circuit board non-metallic powder

The base material of printed circuit board is usually glass fiber reinforced phenolic resin or epoxy resin, and various components are welded on it. The composition is very complex, including a variety of metals, which has high resource recovery value.

Recycling technology of epoxy resin in waste printed circuit boards

At present, the technology of metal extraction and recycling in waste printed circuit boards has been relatively mature. However, there is the problem of recycling the large amount of metal that remains after extraction.

Printed circuit board assembly technology

The performance of reflow heating process: (1) good wettability, (2) reduce the formation of solder ball, (3) less solder spatter when reflow temperature rises sharply, the solder paste will appear almost boiling phenomenon, causing solder particle spatte

Explain the importance of electroplating for printed circuit boards

The interconnection of various plates in electronic facilities often requires the use of PCB plug sockets with spring contacts and a matching preset printed circuit board with connected contacts.

What is PCB flux? Purpose of welding printed circuit board

The use of PCB solder solder has become so common that it is most unusual to see that there is no solder for any PCB to resist covering, except for some home built circuits today, and even many prototype boards have solder solder

Steps for making rigid printed circuit boards

Usually does not contain volatile solvent, low temperature fast curing, can meet the requirements of mass production automation, high production efficiency, good product quality, heat resistant curing flux accounts for more than ten energy.
