2. A-TECH CIRCUITS Co., Ltd. has won the favor of new and old customers at home and abroad. It can be printed with numbers, names, data codes, logos, or other specific information
3. We set a higher and higher standard for the quality of this product.

Multilayer PCB has more than two conductive copper layers which mainly consist of inner layer cores, prepreg layers and copper foils and they’re melted together through heat and pressure. Lamination process is one of the key to control good quality of multilayer PCB, this process requires specific heating and pressure for specific periods of time based on materials used to ensure the PCB board is made properly.

The multilayer PCB is the development of the double sided PCB with increasing complexity and density of components, they allowed the designers to produce highly complex and compact circuits and further development of blind and buried via hole technology has pushed these limits even further. With the requirements of higher precision in various applications, the demands of multilayer PCB keep increasing continuously in recent years. The typical applications of multilayer printed circuit boards include Computers, Data storage, Cell phone transmission, GPS technology, satellite systems and so on.
