Abstract: Photoimageable dry-film for forming a solder mask on the face of a printed circuit board are more easily laminated on the face of the board by effecting evacuation of the entrapped air and a mechanical pressing within a vacuum chamber while avoiding heating of the photoimageable resin layer up to a fluid state. Subsequently the sandwich is heated at atmospheric pressure until the photoimageable resin layer (4) is made fluid to conform it to the surface of the board under the effect of the atmospheric pressure. Retention of a cover sheet (3) of the photoimageable dry-film (4) up to the moment of heating the pre-evacuated and pressed assembly facilitates the performance of local treatments for preserving the integrity of the film over tenting zones about holes of the printed circuit board. The method is effective either with conformable thin dry-films as well as with thicker dry-films.

Abstract: A machine peels a protective film (18) off a surface of a photoresist film laminated onto the surface of a printed circuit board (12), being the motion of the boards through the machine continuous. Such a condition is obtained in an effective manner by employing mechanical devices (2) for preventively degrading the adhesion along an edge zone of the laminated board (12) that, instead of acting onto the leading edge thereof substantially normal to the direction of advancement, act along two opposite lateral edges of the protective film (18), substantially parallel to the direction of advancement of the board through the machine, and are themselves a functional part of the board advancement system (conveyor). The mechanical devices (2) for degrading the adhesion along the two lateral edges of the protective film, eventually on both faces of the board, may be common knurls that act along the side edges of the protective film when the board passes at a substantially constant speed through the machine. According to the preferred embodiment, nozzles, (9, 10) suitable to blow air a relatively low pressure may be present in the separation gaps between two adjacent knurling wheels.
