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

... 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 SHOP | 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 SHOP | 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 SHOP | 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 SHOP | 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 SHOP | 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 in | PRINTED CIRCUIT BOARDS SHOP | favour of applying tin chemically. One advantage is the uniform smoothness of the surface. This feature ...

... regulations of the client, so that a permanent feedback for all involved persons is given. Apart from the technical pre-production the quality assurance maintains | PRINTED CIRCUIT BOARDS SHOP | the updating utility by means of internal indexings of the documents. - | THIS SEQUENTIALLY DOCUMENTED PRODUCTION | order serves on the one hand the | PRINTED CIRCUIT BOARDS SHOP | evaluation of individual requirements of the product and on the other hand as result of the production achievement of the collection of actual quality criteria | PRINTED CIRCUIT BOARDS SHOP | in the sense of the SPC (statistical process control). The interprocessual examinations are made in accordance with inspection schemes. As a final output examination our | PRINTED CIRCUIT BOARDS SHOP | quality assurance provides central an output report on the basis of the systematically collected data, that documents the fulfilment of the assured characteristics. - | | PRINTED CIRCUIT BOARDS SHOP | WITH THE ELECTRICAL FINAL | inspection pcb´s are examined for short-circuit and interruption. The test system is loaded with the gerber data which is provided | PRINTED CIRCUIT BOARDS SHOP | to us from the ...
