wholesale China pcb plating half depth company top supplier

Company Advantages
1. The quality of A-TECH press fit pins pcb is guaranteed to meet the standards of the heatsink industry, including the safety and electricity performance standards. Its working panel is coated with a photo-sensitive epoxy-based ink, which can ensure its insulation resistance
2. It is a highly efficient product which is ideal for heat transfer in linear air-flow environments. Many customers have used it in their electronic products. With a solder mask, it enjoys a good electrical insulation property
3. The product is not susceptible to chemicals. The chromium element has been added as an agent to provide corrosion resistance. Its robust structure allows it to be used in harsh environments
4. The product has the advantage of chemical resistance. It can withstand the impacts of chemicals such as acids, salts, and alkalis. It has increased power densities which guarantee its long service life
5. This product features robustness. The metal material is well known for its robust property especially when exposed to strong impact, it is not easy to bend or crack. The product can be resistant to corrosion

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.
