... a conductive polymer that may be produced either in the horizontal mode using specially designed horizontal processing equipment or in the vertical mode using | PRINTED CIRCUIT BOARDS FABRICATORS | a standard immersion type plating line. The DMS-E system consistently delivers highly reliable plated through-holes on all commonly used laminate materials, PWB complexities and in | PRINTED CIRCUIT BOARDS FABRICATORS | a variety of operating conditions. Production-proven in both vertical and horizontal process equipment, the versatile system yields total process cost reduction Panel Plating a Flash | PRINTED CIRCUIT BOARDS FABRICATORS | of Copper The panels are online in a wet state transferred to our automatic electrolytic copper plating lines to get a flasch of copper.. The | PRINTED CIRCUIT BOARDS FABRICATORS | panels are attached to plating racks. When the racks are moved to the loading station, the system computer instructs the hoist to pick up the | PRINTED CIRCUIT BOARDS FABRICATORS | rack and begin the plating cycle. The copper plating time is approximately one hour. Electrolytic copper of minimum thickness 12 microns is deposited on the | PRINTED CIRCUIT BOARDS FABRICATORS | surface of the panel and ...

A special hand screening area is available for such applications. | PRINTED CIRCUIT BOARDS FABRICATORS | This hand screening does add additional cost to the product. Curtain Coat LPI Mask (alternativ) Solder mask is also be applied using a curtain, single | PRINTED CIRCUIT BOARDS FABRICATORS | sided coating system. The equipment is designed specifically for the application of liquid photoimagable (LPI) solder mask. Dry LPI Mask Liquid photoimagable solder mask is | PRINTED CIRCUIT BOARDS FABRICATORS | an epoxy polymer material which is cross-linked or cured by the application of heat. Since the solder mask cannot be imaged in a liquid state, | PRINTED CIRCUIT BOARDS FABRICATORS | the screened solder mask must be dried without actually curing the material. Drying is done in an oven designed specially for this application. A single | PRINTED CIRCUIT BOARDS FABRICATORS | heater plenum and a unique baffle system effectively removes the solvent from the liquid solder mask without starting the cross-linking action. Screened panels are manually | PRINTED CIRCUIT BOARDS FABRICATORS | loaded into the conveyorized oven as they come ...

In addition, the test for soldering ability showed that emphasis | PRINTED CIRCUIT BOARDS FABRICATORS | should be placed on a suitable flux agent, as this, in addition to the thermic effect, also leads to the removal of the OSP layer. | PRINTED CIRCUIT BOARDS FABRICATORS | In Europe, there is a lack of enthusiasm for OSP, especially due to the great demands made on the flexibility of lead-free surfaces, plus the | PRINTED CIRCUIT BOARDS FABRICATORS | need for multi- soldering using a variety of thermic processes with standard flux agents. DIFFERENT INDUSTRIAL STRUCTURES – DIFFERENT SURFACES It is, therefore, not surprising | PRINTED CIRCUIT BOARDS FABRICATORS | that, especially in Asia, OSP is as popular as chemical tin is in Europe, or chemical silver in the US. An environment of mass production | PRINTED CIRCUIT BOARDS FABRICATORS | with long-term planning – often in-house – using a single thermic soldering process makes OSP the absolute favourite. As long as Europe is oriented towards | PRINTED CIRCUIT BOARDS FABRICATORS | flexible, small series equipment with a variety of special technical ...
