Multilayer Circuit Boards Prototype Materials for printed circuit boards deposited on the surface of a copper-clad base material that prevent the removal by etching of the conductive areas they cover.

... provided unsatisfactory results, meaning that the lead-free problem has yet to be resolved. The chemical nickel-gold procedure (Imm NiAu) was unsuccessful due to high | MULTILAYER CIRCUIT BOARDS PROTOTYPE | costs, as was chemical tin. Both procedures have proven to be very complicated and sensitive in the further course of processing management. Lead-free solderings also | MULTILAYER CIRCUIT BOARDS PROTOTYPE | have serious disadvantages, as hot air tin surfacing exposes the multi-layers to higher processing temperatures and copper leaching effects. would briefly like to explain why | MULTILAYER CIRCUIT BOARDS PROTOTYPE | chemical silver is the lead-free procedure of the future, and why it will be the focus of our future investments in the field of surface | MULTILAYER CIRCUIT BOARDS PROTOTYPE | refinement: UNPROBLEMATIC WASTE WATER PROCESSING Similarly to chemical tin surfacing, it is a non-electrical, auto-catalytic procedure based on the contrasting electro-negativity of copper and the | MULTILAYER CIRCUIT BOARDS PROTOTYPE | more “precious” silver. The advantages of this processing manner compared with chemical tin are fewer processing steps and lower rinsing temperatures ...

... CIRCUIT BOARDS | Drawings Drawings must be supplied with each new job and should contain the following information to ensure that the finished board | MULTILAYER CIRCUIT BOARDS PROTOTYPE | is to your requirements. - Always required even when a drill file is supplied, to enable inspection of panels immediately after drilling and finished boards | MULTILAYER CIRCUIT BOARDS PROTOTYPE | prior to despatching. Hole sizes must be clearly represented with distinct differences between each size. Tolerances are not required unless different to our standard of | MULTILAYER CIRCUIT BOARDS PROTOTYPE | +0.1 / -0.05 mm. - Preferred with | OVERALL MECHANICAL DIMENSIONS | including notches, cutouts and slots. Also preferred is a positioning (datum) dimension (drilled | MULTILAYER CIRCUIT BOARDS PROTOTYPE | hole is best). Tolerances are not required unless different to our standard of + / -0.25 mm. | OTHER INFORMATION REQUIRED FOR ALL BOARDS INCLUDES: | MULTILAYER CIRCUIT BOARDS PROTOTYPE | | board thickness (standard = 1.6mm) base copper thickness (std = 18mm) solder mask colour (std = green) solder mask type (std = liquid photoimageable) | MULTILAYER CIRCUIT BOARDS PROTOTYPE | component legend colour (std = white) bare board ...
