General Description
A 6-layer ultrathin printed circuit board (PCB) is built on an FR-4 substrate with a Tg of 135°C, specifically designed for GPS tracking applications. With a thickness of just 0.6 mm, the PCB features a green solder mask (Taiyo) and immersion gold on the pads, without any silkscreen. The base material is sourced from Taiwan's ITEQ, providing one PCB per panel. The vias, measuring 0.25 mm, are resin-filled and capped (via in pad), with blind vias extending from the top layer to inner layer 1 and buried vias connecting inner layer 3 to inner layer 4. Fabrication complies with IPC 6012 Class 2 standards using supplied Gerber data, and each shipment contains 50 panels.

Via in Pad Technology
As circuit boards become denser and more interconnected, the need for efficient routing has led to the development of via in pad technology. This method involves plating through holes that are filled with insulating resin, followed by drying, grinding, and electroplating. As a result, the entire surface of the PCB is coated with copper, eliminating visible via holes.
The benefits of via in pad technology include improved electrical performance and reliability, shortened signal transmission paths, reduced inductive and capacitive reactance, and minimized electromagnetic interference.
Basic Process of Via in Pad
Drilling and Filling: Holes are drilled and filled with insulating resin.
Drying and Grinding: The surface is dried and ground to a smooth finish.
Electroplating: The entire surface receives a copper coating, enhancing conductivity.
This innovative approach is essential for modern high-performance electronic products.
