... drill dust or debris in the holes. The high pressure rinse is followed by a final fresh water rinse. The panels are then dried | PRINTED CIRCUIT BOARDS MAKER | in preparation for electroless copper deposition. The scrubbing line is equipped with an automatic loader and unloader and may be run unattended Alkaline Permanganate: Smear | PRINTED CIRCUIT BOARDS MAKER | Removal Before direct metallization, the drilled holes on multilayers have to be desmeared. The main purpose of this treatment is to remove any epoxy smeared | PRINTED CIRCUIT BOARDS MAKER | onto the edge of the inner layer copper pads whilst drilling. The smear is the result of a hot drill melting the epoxy resin and | PRINTED CIRCUIT BOARDS MAKER | spreading it across the hole wall during its up and down motion. The epoxy smear causes poor and in some cases non electrical continuity to | PRINTED CIRCUIT BOARDS MAKER | the innerlayers as well as poor adhesion of the plated copper to the hole wall. In desmear, the chemical attack is designed to remove only | PRINTED CIRCUIT BOARDS MAKER | the surface smear of resin from the hole wall, without attacking the wall structure itself. For most needs desmearing is ...

(measured as a package) Great emphasis was put on automation for stacking and for enclosed separation sheet | PRINTED CIRCUIT BOARDS MAKER | circulation. The flow directions for the transport sheets and separation sheets are intentionally interrupted after de-stacking, enabling cleaning of sheets or buffering of empty stacks. | PRINTED CIRCUIT BOARDS MAKER | With the aid of vacuum, a lot less pressure is required, resulting in less distortions and virtually no air entrapment. Another plus is that very | PRINTED CIRCUIT BOARDS MAKER | little resin flows from the multilayer. The finished result is a board with lower dielectric constant, preferred for impedance controlled boards which are becoming very | PRINTED CIRCUIT BOARDS MAKER | dominant in todays market. Lay-Out When the bonding cycle is complete, the packages are removed from the the vacuum lamination press, split down. -------------------------------------------------------------------------- Multilayer-Lamination-Press-Department | PRINTED CIRCUIT BOARDS MAKER | Multilayer Vacuum Transfer Press Bürkle: Multilayer vacuum ...
