Company Advantages
1. Strict examining system of A-TECH impedance pcb will be carried out throughout the production process. The final piece of the product has to go through a complete set of inspection in terms of stamping, cutting, and polishing quality.
2. The product is bacteria resistant. It has an antibacterial layer that consists of non-toxic ingredients, such as medical zinc oxide or calcium carbonate.
3. The product is flame-retardant. Being dipped into the special treating agent, it can delay the temperature from going on.
4. This product makes it easier for workers to reach their goals in less time. It plays an important role in alleviating the fatigue and stress of workers.

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.
