Product Comparison

A-TECH's Multilayer PCB has better performances in the following aspects.

Company Advantages
1. A-TECH single layer pcb has passed a variety of inspections. They mainly include length, width, and thickness within the approval tolerance, the diagonal length, angle control, etc.
2. This product is able to retain its original appearance. Thanks to its protective surface, the effect of humidity, insects or stains will never destroy the surface.
3. One of the benefits of this product is its full lifetime cost, including ongoing costs of maintenance and operation. It can help save a lot of money each year.

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.

The benefits of multilayer PCB

● Increased flexibility
● Higher assembly density
● Smaller size(considerable savings on space)
● Easier incorporation controlled impedance features
● Reduces the need for interconnection wiring harnesses(Reduces overall weight)

A-TECH is an experienced multilayer PCB manufacturer which own complete multilayer PCB manufacturing process in house from inner layer, vacuum lamination to surface finishes, it brings us more advantages in the competition of global market shares for multilayer printed circuit boards on quality, price and lead time.
