Multilayer PCB manufacturing methods include the plated-through hole (PTH) and high-density interconnect (HDI) methods, both achieved by combining different processes to realize the circuit board structure. Currently, the most widely used method is the PTH method, which has been developed and refined over more than half a century. The PTH method is mature in terms…

When designing PCBs, routing is essential. The quality of the routing affects the aesthetics, production cost, circuit performance, heat dissipation, and device optimization. This article provides a comprehensive guide on PCB routing techniques: 1. The routing length should include the length of vias and solder pads. 2. The preferred routing angle is 135°. Arbitrary angles…

In PCB fabrication, the transition from a digital design to a physical product involves several crucial steps. One of the most important phases in this process is the preparation and submission of the correct files. These files contain all the necessary information for manufacturing the printed circuit board to precise specifications. Below is an overview of…
