Flatness and life expectancy
It is difficult to flatten the thin pad by the process of straight tin injection, which brings difficulties to SMT mounting. The shelf life of extra tin-spray plate is very short. Gilding neatly solves these problems

Why should PCB circuit board sink gold and gold plating, what is sink gold and gold plating
The most fundamental difference between gold plate and gold plate is that gold is hard gold (wear-resistant), gold is soft gold (not wear-resistant).
What's the difference between PCBA and PCB
PCB=Printed Circuit Board ; PCBA=Printed Cirruit Board +Assembly.That is to say, PCB empty board through SMT, and then through the DIP plug-in of the whole process, referred to as PCBA.
Take you to understand the rework process in PCBA
First, the difference between rework and maintenance, second, rework process objectives.1, controllable, reliable, repeatable process, which can be adjusted when necessary, 2, efficient process, can be quickly and easily carried out in the production envi
PCB board online order
After determining PCB related selection factors, the payment method should be selected, including whether to issue bills, express logistics, packaging type and flying needle test. If there are special requirements, the information should be noted.
Damage analysis of PCB circuit board deformation and improvement measure
Basically, V-Cut is the culprit of damaging the structure of the board, because V-Cut is in the original a large sheet of the board to cut out grooves, so the V-Cut place is prone to deformation.
Influence of surface treatment technology on wideband PCB loss
Surface treatment is very necessary for PCB circuit processing. It not only provides a smooth weldable surface for component welding, but also provides protection for the copper conductor of the PCB.
PCB board microhole mechanical drilling what problems need to pay attention to
it is critical that your PCB components be accurate and functional. Therefore, dealing with reliable PCB component manufacturers and service providers is critical.
Networking and communication The 4 most commonly used materials in PCBS
The following article illustrates the different materials used to manufacture PCBS for networking and communication applications. Again, various useful features and characteristics of these materials are discussed in the post. Read on to learn more.
Rf PCB routing criteria are used to suppress noise
There are many issues to consider in RF design, as the correct design choice depends largely on the primary operating frequency and whether the RF board is really a mixed signal board.
Reading leads to the foot to do "four understanding"
Reading lead foot is a common office reading integrated circuit diagram, is also the most close office. Know clearly inside the composition of the block diagram, can increase the depth of the introduction of the foot function awareness.
Automotive sensor market will continue to hot PCB copy board to accelerate domestic high-end intelligent
