Multilayer PCB Has More Than Two Conductive Copper Layers

Multilayer PCB recieve more than a couple of conductive copper tiers which mainly are made up of inner layer cores, prepreg tiers and copper foils and they? re melted together by means of heat and stress. Lamination process is one of the key to handle top quality of multilayer PCB, this procedure requires specific heat and pressure with regard to specific periods of time centered on materials accustomed to ensure the PCB board is manufactured properly.

The multilayer PCB is the development of typically the double sided PCB with increasing difficulty and density regarding components, they allowed the designers to be able to produce highly complicated and compact brake lines and further development of blind plus buried via gap technology has forced these limits actually further.

With typically the requirements of higher precision in several applications, the demands associated with multilayer PCB maintain increasing continuously lately. The typical applications of multilayer printed circuit boards consist of Computers, Data safe-keeping, Cell phone tranny, GPS technology, satellite television systems and thus on.

multilayer pcb A-TECH is usually an experienced multilayer PCB manufacturer which often own complete multilayer PCB manufacturing process in house from inner layer, machine lamination to surface finishes, it brings us more positive aspects in the opposition of global marketplace shares for multilayer printed circuit panels on quality, price and lead period. Currently the proportion of multilayer PCB we manufactured is more than 65%.

HDI PCB, the complete name is High Density Interconnect PCB, it requires a lot higher wiring denseness with finer search for and spacing, more compact vias and higher connection pad denseness. Blind and buried vias? design is 1 of their designated feature. HDI PCB are widely applied for Cell phone, tablet computer, camera, GPS, LCD module in addition to other different location.

A-TECH CIRCUITS gives HDI PCB production services to around the world customers in the particular top end automotive business, medical camera business, mobile, computing and defense industry.

Currently the advanced HDI technology we used include: “Direct Laser Drill”(DLD) is going of copper layer by direct CO2 laser irradiation, out-do additional laser drilling with conformal cover up, the copper direct laser drilling is capable of providing higher accuracy, better hole quality and far better efficiency for HDI projects. “Copper Filled” for special bunch microvia, “Laser Immediate Imaging”(LDI) is particularly designed for fine line technology, in order to eliminate dimensional stability problem of artwork caused by environmental and material concerns.
