With LPI solder mask, circuit board via tenting has come to mean that the mask will cover the pad and enter the hole, but will not close the hole completely. Dry film use has droped considerably in the industry over the last few years in favour of liquide photo imagable materials. In the traditional way, it is first curtain coat (or spray or screen print), dry, then coat the other side, dry, then go to the imaging area using film (which also has to be prepared), or go to the LDI, and then finally you have the development step to come to the solder mask image. WonderMask P is a temporary, peelable solder mask designed to withstand fluxing, wave soldering and cleaning operations. Louwet: A lot of. In the past, masks were applied in sheets called Dry Film, but with the advent of Liquid Photo Imageable masks and techniques, Dry Film is rarely used today. Thermal Curable Permanent Hole-Plugging Material; Thermal. Properly selected underfill material blocks out part of the thermally induced deformation in the joints to such an extent that the fatigue damages are no more clearly dependent on the distance of the joint from the neutral point of the structure.
