At present, there are two general FPC welding processes, one is tin press welding, and the other is manual drag welding.

According to the number of layers, single-sided, double-sided and multilayer circuit boards are divided according to the circuit layer inside.

PCB proofing, as a component of high-precision electronic products, has been a very common existence in life. However, we all know that domestic professional PCB proofing design needs different point settings in different stages, and large grid points will be used for device layout in the layout sta......

Flow chart of single-sided FPC circuit board: engineering documents - copper foil - Pretreatment - press dry film - exposure - Development - etching - film stripping - AOI - Pretreatment - coating film (or ink printing) - pretreatment before electroplating - electroplating - post electroplating - re......

PCB manufacturers show you the evolution of PCB production process. In the 1950s and early 1960s, laminates mixed with different types of resins and various materials were introduced, but PCB is still single-sided. The circuit is on one side of the circuit board and the component is on the other sid......

At present, most of the holes drilled in the double-sided flexible printed board are still drilled by the NC drilling machine. The NC drilling machine is basically the same as that used in the rigid printed board, but the drilling conditions are different. Because the flexible printed board is very ......
