Solder mask is applied onto PCB surfaces through a range of additive methods: LPI – Liquid Photoimageable Ink Most common method Rolled, sprayed or screen printed Precise exposure cures and defines openings Powder Coating Electrostatically coated with powder ...
PCB solder mask prevents oxidation, a reaction when a metal is exposed to air in the atmosphere. During oxidation, the metal reacts with air losing its chemical properties and starting to rust. So, to prevent PCB from oxidation, applying a solder mask is crucial. Also, Solder Mask offers p...

Solder Mask refers to the printing of solder mask ink on the surface of the PCB where soldering is not required. Due to the fluidity of solder paste at high temperatures when soldering printed circuit boards. Therefore, a layer of solder resist must be printed where soldering is not required ...
First, the panel forPCB productionis cleaned thoroughly. This is to make sure that no dust particles found its way underneath yoursolder mask. Next, these panels would be covered completely on one or the two sides using your LPI solder mask ...
The solder mask is generally Fluid UV Photo-imageable Ink with environment-friendly, red, blue, yellow, white, black as well as purple shades, eco-friendly ought to be one of the most frequently utilized ones. As well as according to those shades readily available, there are some factors ...
1. When printing solder mask ink on the PCB circuit board, the pretreatment is not done properly. For example: there are stains, dust on the surface of the PCB board, or some areas are oxidized. It is the easiest to solve this problem. It only needs to do the pre-treatment again, ...
