A-TECH A-TECH via in pad company for sale

Company Advantages
1. via in pad mainly contains press fit pins pcb material. A smooth part is added on its PTH line to reduce the roughness of through hole
2. The product is able to be used in a variety of applications. It totally conforms to the UL Flame Rating of 94V-0
3. The product is 100% formaldehyde free. During the preliminary stage, all of its material and pigment have been tested and proved toxic-free. Its solderable surface is protected from the oxidation

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. Situated in an advantageous geographical setting, the factory is close to some crucial transportation hubs. This enables the factory to save a lot in transportation cost and shorten delivery time.
2. Our operating principle is 'performance of contract, performance of commitment'.
