PURPOSE: To reduce a scrape-off phenomenon caused by a squeegee and to perform uniform printing even in the moving direction of the squeegee, in a metal mask used when cream solder is printed on a printed circuit board, by forming an opening part of a metal part from a plurality of ...
Dry film photo imageable solder mask is more like a sticker or two stickers held together with the solder mask. One side is peeled off and the remaining material goes over the entire board mask-side down. The areas where the metal is to remain exposed are masked off before curing it with...
(PCB) we often see. It is also called a solder resist or solder-top mask, which is a thin layer of polymer lacquer to protect copper traces from oxidation and prevent short circuits. In fact, besides the green cover, there are other colors of the solder mask such as white, blue, ...
PROBLEM TO BE SOLVED: To provide a metal mask for printing a cream solder capable of improving reliability of printability and solderability with a simple constitution without thinning a screen in thickness.;SOLUTION: Ends S1, S2 of an opening 12a of the metal mask 12 in a longitudinal directio...

Solder masks protects metal elements on a PCB from oxidation and electrical "bridging" between solder pads. Learn about the best solder stop mask PCB approach for your project.
Solder mask is a thin layer of polymer used on PCB to prevent solder joints from bridging. The solder mask can also prevent oxidation and be applied to the copper trace on the PCB board.
