What are The Benefits of Using Solder Mask to Plug Holes?

We've already learned about the acceptance criteria for the soldermask process in all its aspects, so today let's learn about the inspection process for those working in the factory.

Following up on the last news, this news article continues to learn the acceptance criteria for the quality of PCB solder mask process.

Following up on the last news, this news article continues to learn the acceptance criteria for the quality of PCB solder mask process.

Today we will learn that, in the PCB solder mask, specifically should be in accordance with which standards to process.

In the PCB solder resist production process, sometimes encounter ink off the case, the reason can basically be divided into the following three points.

Printed circuit board in the sun resistance welding process, is the screen printing after welding resistance of the printed circuit board with a photographic plate will be covered by the pad on the printed circuit board

In general, the solder mask thickness in the middle position of the line is generally not less than 10 microns, and the position on both sides of the line is generally not less than 5 microns, which used to be stipulated in the IPC standard, but now it is not required, and the specific requirements of the customer shall prevail.

The solder resistance film must have good film formation to ensure that it can be uniformly covered on the PCB wire and pad to form effective protection.

In the PCB processing and production process, the solder mask ink coating coverage is a very critical process.

Does PCB solder mask colour have any effect on the PCB?

Green ink can do smaller error, smaller area, can do higher precision, green, red, blue than other colors have a higher design accuracy
