PCB Lecture Hall: What is a multilayer board??

The first layer in the middle is laid with multiple GND, several lines can be laid, but do not divide each layer of copper; The second layer of VCC copper in the middle has multiple power supplies laid separately. A small number of lines can be laid, but

PCBA Processing How To Avoid PCB Board Warping?

In order to prevent deformation of many electronic products, the thickness of the board is left at 1.0mm, 0.8mm, or even 0.6mm.

Why are the vast majority of PCB board colors green?

Actively promote the "PCB design - manufacturing - PCBA processing (SMT mount)" one-stop service model, with the goal of "creating the best overall value for the project", to eliminate the inconvenience of multi-party communication, fo...

Analysis of deformation causes caused by PCB board processing

PCB boards are generally stored vertically on shelves during the semi-finished product stage. Incorrect stacking and placement of boards during storage can cause mechanical deformation.

Ten points for attention on PCB board

The outer frame (clamping edge) of the PCB assembly should adopt a closed-loop design to ensure that the PCB assembly will not be deformed after it is fixed on the fixture.
