A-TECH press micro vias pcb durable top supplier

Company Advantages
1. The production of A-TECH press fit pins pcb is smooth-running and efficient. A smooth part is added on its PTH line to reduce the roughness of through hole
2. To meet the most strict standards, A-TECH has its own related quality control system. Being laminated by advanced vacuum lamination equipment, it has a uniform dielectric thickness after lamination
3. The product is tested through a complete and scientific quality management system. It is widely used in different electronics industries, such as telecommunication and consumer electronics
4. The product is 100% qualified as it meets the strict requirements for the quality inspection. It is lead-free and environmental-friendly and has passed SGS test

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.
