You're correct, uV costs 1.7X solvent-based silicone. This high purchased material cost is counter balanced by uV requiring lower thickness due to higher solids and that 60 to 80% of a solvent coating is volitile and goes up the pipe between applicat

Sirs, What are the issues involved when a stencil printer is used for printing solder paste and adhesive? UV-curing of adhesive appears to help reduce slump and spread by forming a tough skin on the adhesive blob deposited on the PCB. Is th
