... SOLDER LEVELING |The process of dipping PCB's into hot liquids, or exposing them to liquid waves to achieve fusion. First, flux is applied to | PRINTED CIRCUIT BOARDS SHOP | the board by dipping or brushing. Then the board is preheated in a liquid (maintained at 250 F). Next, the board is immersed in fusing | PRINTED CIRCUIT BOARDS SHOP | liquid at 430 - 500 F. Finally, it is dipped in another 250 F liquid to cool it and reduce thermal shock. Thin fused coatings | PRINTED CIRCUIT BOARDS SHOP | can be applied. | SOLDER RESISTS (SOLDERMASK) | Coatings which mask off and surface insulate those areas of a circuit where soldering is not desired. | PRINTED CIRCUIT BOARDS SHOP | | STEP AND REPEAT | A method by which successive exposures of a single image are made to produce a Multiple Image Production Master. | | PRINTED CIRCUIT BOARDS SHOP | SUB-PANEL | A group of printed circuits (called modules) arrayed in a panel and handled by both the board house and the assembly house as | PRINTED CIRCUIT BOARDS SHOP | though it were a single printed wiring board. The sub-panel is usually prepared at the board house by routing most of the material separating individual | PRINTED CIRCUIT BOARDS SHOP | modules, leaving ...

... between electrodes. | EPOXY SMEAR | Epoxy resin which has been deposited onto the edges of the conductive pattern during drilling. Also called Resin | PRINTED CIRCUIT BOARDS SHOP | Smear. | ETCH FACTOR | The ratio of the depth of etch (conductor thickness) to the amount of lateral etch (undercut). | ETCHBACK | The | PRINTED CIRCUIT BOARDS SHOP | controlled removal of all components of base material by a chemical process on the sidewalls of plated through holes in order to expose | ETCHING | PRINTED CIRCUIT BOARDS SHOP | | The process of removing unwanted metallic substance (bonded to base) via chemical or chemical and electrolytic means. | ETCHING RESISTS | Materials deposited on | PRINTED CIRCUIT BOARDS SHOP | the surface of a copper-clad base material that prevent the removal by etching of the conductive areas they cover. | EXPOSURE OPERATIONS | The process | PRINTED CIRCUIT BOARDS SHOP | of illuminating the photo-resist coated circuit board to light of the correct intensity and spectral make-up for the correct period of time needed to cause | PRINTED CIRCUIT BOARDS SHOP | hardening (polymerization of the resist. Only specific areas of the resist are exposed, as ...
