Photoresist Barriers Photoresist Barriers - Spray Coating Photoresist - Cheersonic 1. Exploring Lithography: From Printing Lithography is a process technology that uses the principle of photochemical reaction and chemical and powerless etching methods to transfer the pattern on the reticle to the wafer. The principle of lithography originated from photoengraving in printing technology. Unlike printing, the lithography process does not use ink as a medium, but completes the transfer of [...]

Coating Of Circuit Board Flux Coating Of Circuit Board Flux - Flux Spray - Cheersonic The flux must be applied to the underside of the printed board in the most efficient and economical way possible. The flux coating should be uniform and completely cover the soldered parts. If the flux is used in excess, it will not only drip onto the preheater and cause a fire hazard, but also be [...]
