How to select the surface treatment process of HASL, ENIG and OSP for printed circuit boards? After finish the PCB design, we need to choose the surface treatment process of the printed circuit board. At present, the commonly used surface treatment process includes HASL, ENIG and OSP. How should we make a choice between them? Different PCB surface treatment ...
Here are some of the advantages of heavy copper PCB, let’s follow them: 1. Favorable circumstances of Heavy Copper PCB 2. Plating innovation in overwhelming copper permitted a mix of plating and carving which causes in straight sidewalls and immaterial undercut. 3. The substantial copper plating creates high-current circuits and control circuits that watches...

What is a flexible PCB board? Flexible PCB, also called soft board, FPC board, is a kind of pcb, with excellent flexibility. FPC circuit board can complete the overall wiring work on one machine, which can be expanded and moved arbitrarily according to the space layout requirements, reduces the wiring volume, realizes the integration of component assembly an...
Selective plating hard gold pcb is actually an electroplating alloy (that is, plated with Au and other metals), so the hardness will be harder. It is suitable for use in places that require force and friction, and used as the edge contact point of the circuit board (commonly known as ” Gold finger”. Hitech, a profesional electroplating hard gold pcb factory ...
FR-4 Tg170, the material of 12 layers heavy copper printed circuits board which with immersion gold finishing. The copper thickness is 3 Oz for all layers and 0.3 mm min through hole. Hitech offers kinds of heavy copper printed circuit board what can widely use in high power rectifiers. It’s not only conducts various layers of circuits, but also insulates ea...
The copper pcb manufacturing by Hitech, raw material is FR4 TG180 S1000-2 finished gold plating. The thickness of the copper foil is an important factor that affects the characteristic impedance. The greater wire thickness, the smaller impedance, but the range of change is relatively small. In other words, thin copper foil is used to make fine wires to incre...
Rigid-flex PCB board, it is a circuit board that combines flexible and rigid circuit board technology in the application. Most rigid-flex boards are composed of multiple layers of flexible circuit boards, which are attached to one or more rigid boards from the outside and/or from the inside, depending on the design of the application. The flexible substrate ...
Heavy copper PCB boards ( also being called thick copper board, power board etc ) are usually bonded with a layer of copper foil on a glass epoxy substrate. The thickness of copper foil is usually 18μm, 35μm, 55μm and 70μm. The most commonly used copper foil thickness is 35μm. The thickness of copper foil used in China is generally 35-50μm, and there are als...
