... lamination, the panels are automatically loaded on to an accumulator for the next operation. Expose Image The circuit image is transferred on the dry | MULTILAYER BOARDS SERVICES | film resist by placing a positive image film of the circuit directly on the resist and exposing it with UV light. We have two ORC | MULTILAYER BOARDS SERVICES | Opti-Beams automatic exposure systems. Panels are automatically fed into the autoexposure unit.  The panel is aligned to the top and bottom circuit films and a | MULTILAYER BOARDS SERVICES | vacuum pump removes the air between the panel and the film. Exposure is controlled by an integrator located near the panels.The imaging process is carried | MULTILAYER BOARDS SERVICES | out in a controlled environment to minimise the effects of temperature and humidity variation and maximise the yield of quality product. After exposure, the panel | MULTILAYER BOARDS SERVICES | is ejected from the exposure system and loaded onto an accumulator. Developing Image After the panel has been exposed, it is finally developed to remove | MULTILAYER BOARDS SERVICES | all areas of unexposed resist. The chemistry in the developer is controlled by an ...

... desmear. Regardless of the ablation mechanism, high peak powers and short laser pulses give the best microvia results. Each material has a unique ablation | MULTILAYER BOARDS SERVICES | threshold, above which vaporization occurs for a given wavelength and laser fluence (energy/area). | MOST LASER-BASED SYSTEMS | are typically configured for direct microvia formation, | MULTILAYER BOARDS SERVICES | which means that each microvia is drilled one at a time at high speed. With this technique, the size of the focused laser beam usually | MULTILAYER BOARDS SERVICES | defines the size of the microvia or the drilling speed or both. UV lasers often produce the smallest focal spots (5 to 20 microns in | MULTILAYER BOARDS SERVICES | diameter), and when used to form larger vias, the laser beam can either be expanded or trepanned to accommodate the larger diameter. With trepanning, the | MULTILAYER BOARDS SERVICES | laser beam usually moves in a full circle or a spiral pattern, starting from the center of the via and removing material as it spirals | MULTILAYER BOARDS SERVICES | outward to the circumference of the via. Trepanning, however, affects throughput by reducing the ...

... bonded panels are trimmed by en edge trimmer, 4 spindle ball bearing routing maschine and cleaned prior to being released to the next stage | MULTILAYER BOARDS SERVICES | of manufacture. CNC & Laser- Drilling-Department CNC - Driller Guide to Documentation Requirements Images To help you quickly access the services we offer, the following | MULTILAYER BOARDS SERVICES | is a guide to the preferred requirements for producing quality Printed Circuit Boards. Can be supplied as artworks, penplots, photoplots or photoplot files, so long | MULTILAYER BOARDS SERVICES | as the quality and registration of the images is of a standard that will enable a good quality board to be produced. Another important criteria | MULTILAYER BOARDS SERVICES | is the presence of orientation marks within the boundary of board. These marks could be the board reference so long as it cannot be read | MULTILAYER BOARDS SERVICES | from the other side. (This is for your protection to prevent the boards made inside out). Images should comply with design rules that will result | MULTILAYER BOARDS SERVICES | in a board that will meet performance and cost requirements. - Scale must be given, tapes ...
