This time let’s talk about the electrical testing methods of circuit boards, there are: Dedicated,Universal Grid,Flying Probe, non-contact electron beam, conductive cloth (plastic), Capacity and...

A 300mm wafer is 12 inches in diameter. When using a chip that is 1 square centimeter, a 300mm wafer includes approximately 706 chips. The 300mm wafer has 2.25 times the wafer area than a 200mm wafer...

Today let’s have a look at the PCB design and cost controlling, in order to allow the PCB cost the lower the better, there are many design factors must be taken into considerations:1, T...

BOM and parts list are important documents in the production of PCBA, but they have obvious differences in several aspects.BOM is bill of material, which helps the computer identify the structure of t...

Today, the use of ENIG is more and more extensive, which is mainly used for the surface treatment of the PCB, in order to prevent the surface of copper oxidation or corrosion.Why does ENIG start to po...

What is the FPC panel? In fact, the shipments of FPC (flexible pcb) are single piece, there is little make-up panel shipments, unlike rigid PCBs are most panel shipment.FPC (flexible printed circuit b...

FPC three main features1、Deflection of flexible circuits and reliability of the current FPC are: single-sided, double-sided, multilayer flexible and rigid flexible board four boards. Fl...

In the life of flexible pcb issues are concerned, besides the both ends of the flexible pcb to rigid pcb or the connector for connection problems, for the flexible pcb is the ultimate s...
