Comments Off on Multilayer PCB Has Even more Than Two Conductive Copper Layers

Multilayer PCB recieve more than two conductive copper tiers which mainly are made up of inner level cores, prepreg tiers and copper foils and they? lso are melted together by means of heat and pressure. Lamination process is one of the key to manage top quality of multilayer PCB, this method requires specific heat and pressure for specific amounts of time based on materials utilized to ensure the PCB board is produced properly.

The multilayer PCB is typically the development of typically the double sided PCB with increasing complexity and density of components, they allowed the designers to be able to produce highly complex and compact brake lines and further growth of blind and buried via hole technology has pushed these limits even further.

With typically the requirements of higher precision in various programs, the demands of multilayer PCB keep increasing continuously recently. multilayer pcb The typical apps of multilayer published circuit boards consist of Computers, Data storage space, Cell phone transmission, GPS technology, satellite tv systems and so on.

A-TECH will be an experienced multilayer PCB manufacturer which often own complete multilayer PCB manufacturing process in house through inner layer, vacuum lamination to surface area finishes, it provides us more benefits in the competition of global marketplace shares for multilayer printed circuit planks on quality, price and lead period. Currently the proportion regarding multilayer PCB we manufactured is even more than 65%.

HDI PCB, the complete title is High Density Interconnect PCB, it needs very much higher wiring density with finer trace and spacing, smaller sized vias and increased connection pad denseness. Blind and smothered vias? design is one of their noticeable feature. HDI PCB are widely utilized for Cellular phone, pill computer, digital camera, GPS NAVIGATION, LCD module and other different area.

A-TECH CIRCUITS offers HDI PCB producing services to around the world customers in typically the top quality automotive business, medical computer market, mobile, computing and defense industry.

Currently the advanced HDI technology we applied include: “Direct Laserlight Drill”(DLD) is drilling of copper level by direct CO2 laser irradiation, compare to additional laser going with conformal cover up, the copper immediate laser drilling is capable of providing higher accuracy, better opening quality and far better efficiency for HDI projects. “Copper Filled” for special bunch microvia, “Laser Immediate Imaging”(LDI) is specifically designed for fine line technology, to be able to eliminate dimensional stableness problem of art work caused by ecological and material issues.
