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

... | The procurement of PCBs often leads to the question as to which surface protection is the right one. This is partly due to | PRINTED CIRCUIT BOARDS PROTOTYPE | the changing technical demands on PCBs in further processing. Also, as of 1. 6. 2006, EU-Regulations restricting the use of dangerous materials in electronic appliances | PRINTED CIRCUIT BOARDS PROTOTYPE | are to include the prohibition of materials containing lead, and is, therefore, another reason why alternative surfaces have been developed. One of these is immersion | PRINTED CIRCUIT BOARDS PROTOTYPE | tin. PROCEDURE A layer of tin is applied to the PCB by means of a special process, in which the copper atoms of the exposed | PRINTED CIRCUIT BOARDS PROTOTYPE | conductors and contact areas are exchanged for tin atoms by adding thiourea. The chemical reaction ends when the copper surface is 0,6 to 1,2 my. | PRINTED CIRCUIT BOARDS PROTOTYPE | Between the tin and copper layers there is an inter- metallic copper-tin phase after this process, i.e. blended metal. There are a number of reasons | PRINTED CIRCUIT BOARDS PROTOTYPE | in favour of applying tin chemically. One advantage is the uniform smoothness of the surface. This feature enables ...
