A-TECH thick copper buried vias pcb hot-sale top supplier

Company Advantages
1. As our buried vias pcb are made of press fit pins pcb, they are all press fit pins pcb. The inner layer core of the product is chemically treated for improved adhesion of the copper surface
2. A-TECH CIRCUITS Co., Ltd. will strive to satisfy customers, the general public and the people in the countries (regions) where the business is located. A smooth part is added on its PTH line to reduce the roughness of through hole
3. Practice has shown that the products developed by A-TECH CIRCUITS Co., Ltd. have played a significant role in buried vias pcb field. It stands out for its impact endurance performance

Via In Pad (VIP) technology refers to the vias in SMD pad or BGA pad due to small space for layout, in order to avoid the solder paste flow into inner layer or the other side in assembly production, basically this type of via need to be plugged with resin and plate copper over to cap the via to make it invisible.

Via in pad technology is widely used in high density PCBs, especially for the PCBs that require a limited BGA space and are focused on heat transfer and high speed design. Although blind holes and buried holes help increasing density and save space on the circuit boards, through holes are still the best choice for thermal management and high speed design elements.

The advantages of Via In Pad technology

● Suitable for fine pitch BGAs
● Improved thermal dissipation
● Provides a flat, coplanar surface for component attachment
● Leading to higher density of PCBs and promoting space saving
● Overcomes high speed design issues and constraints.
● Meets closely packed placement requirements.

The Via In Pad technology is defined in IPC standard with IPC-4761 VII

A-TECH manufactured lots of multilayer PCBs with Via In Pad designs Both in BGA Pads or in other SMD Pads, we’re able to plugged vias fully and then plated copper over to make the surface of pad as flat as other pads without dimples.

Company Features
1. A-TECH CIRCUITS Co., Ltd. produces and manufactures under customer OEM brand and under our own brand. We invest a lot in our production facilities and constantly upgrade them each year, which enables us to improve operational efficiency for our orders and raise productivity.
2. We have built a professional quality inspection team. They mainly take charge of quality insurance from the product development, raw material purchasing, and production to the final product shipping. This enables us to keep improving the first pass yield.
3. There have been many cooperations with large domestic companies at home and abroad. At the moment, our customers are mainly from Europe, Asia, South America, Middle East, Africa, etc. In order to protect the planet from exploitation and conserves natural resources, we are sparing every effort to upgrade our packaging way that features fewer resources used.
