... Screened panels are manually loaded into the conveyorized oven as they come off the screen printer. The dried panels are automatically loaded on to | PRINTED CIRCUIT BOARDS MAKER | an accumulator for cool down and availability to the imaging operation. Image LPI Mask Dried solder mask is imaged in a manner similar to that | PRINTED CIRCUIT BOARDS MAKER | used for imaging the circuitry. Phototools containing black areas where the solder mask is to be removed are placed in direct contact with both sides | PRINTED CIRCUIT BOARDS MAKER | of the panel. The panel is then exposed to UV light. The amount of light used is controlled by an integrator. Printing is done with | PRINTED CIRCUIT BOARDS MAKER | a semi-automatic dual drawer printer. While one drawer is being loaded with a panel and phototools, the other is inside the machine being exposed. This | PRINTED CIRCUIT BOARDS MAKER | dual drawer printing system runs at the same rate as the screen printer to insure continuous flow. Develop LPI Mask After the panel has been | PRINTED CIRCUIT BOARDS MAKER | exposed, it is placed in a vertical developer. The unexposed solder mask is dissolved in a high pressure spray of developing ...

... DIRECT METALLIZATION SYSTEM FOR PRINTED CIRCUIT BOARDS | Features/Benefits Selective to Dielectric and Glass Total Process Cost Reduction Environmentally Sound Excellent Copper-to-Copper Adhesion and | PRINTED CIRCUIT BOARDS MAKER | Through-Hole Coverage Horizontal and Vertical Process Compatibility No Hole Size, MLB Layer Count or Aspect Ratio Limitations Suitable for PTH Innerlayer or Microvia Metallization CHARACTERISTICS: | PRINTED CIRCUIT BOARDS MAKER | - excellent copper to copper adhesion - no additional etching will be necessary for copper-cleaning - no residuals in blind-micro-Via´s The DMS-E direct metallization system | PRINTED CIRCUIT BOARDS MAKER | selectively deposits highly conductive polymer on dielectric resin and glass areas without the use of electroless copper. The formaldehyde-free, environmentally sound technology provides fast and | PRINTED CIRCUIT BOARDS MAKER | uniform coverage of the plated through-hole. DMS-E selective catalyzation ensures excellent copper-to-copper adhesion at the innerlayer junctions on multilayers. Innerlayer and outerlayer copper surfaces remain | PRINTED CIRCUIT BOARDS MAKER | pristine, ...

... days and double-sided pressings only 7 ! ( Minimum charge: 10% of order value). So far, express services have been mostly in the realm | PRINTED CIRCUIT BOARDS MAKER | of prototype manufacturers, but RMP is on offer to all customers who recognise the market opportunities resulting from accelerated product launches or speedier completion of | PRINTED CIRCUIT BOARDS MAKER | orders. The following brief feature describes the manufacturing concept that we have developed to achieve just such a solution: | TEST US | Apart from | PRINTED CIRCUIT BOARDS MAKER | technical specialisation, the market in multilayer business is divided largely into two groups: those that manufacture in the largest possible series, and those that produce | PRINTED CIRCUIT BOARDS MAKER | prototypes and mini series in the fastest possible time in order to encourage the development of new products. Their strengths, however, are also their weaknesses. | PRINTED CIRCUIT BOARDS MAKER | The fast producers must remain small in order to be flexible, whereas the volume of orders received by the large producers awakens acquisitive interest from | PRINTED CIRCUIT BOARDS MAKER | the even larger international ...
