PCB circuit board, as a support for electronic components, has a wide range of applications and excellent heat dissipation and insulation characteristics. According to the editor's understanding, there are four commonly used materials for PCBs: FR-4,...…
Via is one of the important components of multi-layer PCB, and the cost of drilling holes usually accounts for 30% to 40% of the PCB manufacturing cost. Simply put, every hole on a PCB can be called a via. From a functional perspective, vias can be d...…
Via is one of the important components of multi-layer PCB, and the cost of drilling holes usually accounts for 30% to 40% of the PCB manufacturing cost. From a design perspective, a through-hole is mainly composed of two parts: a drill hole in the mi...…
Please share your technical knowledge on via holes and back drills in PCB circuit boards. 1、 In high-speed PCB design, through-hole design often requires the use of multi-layer PCBs, and vias are an important factor in multi-layer PCB design. The vi...…
High speed PCB design generally uses multi-layer circuit boards, which are actually composed of several etched single or double boards laminated and bonded together. Compared with single-layer and double-layer circuit boards, multi-layer circuit boar...…
In the pattern electroplating method of multi-layer circuit board manufacturers, the power circuit pattern is prone to side corrosion during the entire etching process, resulting in a suspension layer of tin lead alloy plating that is suspended in th...…
What is a multi-layer circuit board? The dual panel is the middle layer of the medium, with wiring layers on both sides. A multi-layer circuit board is a multi-layer wiring layer with a dielectric layer between every two layers. The dielectric layer ...…
