How to achieve the copper thickness of the heavy copper board | YMSPCB

Can PCB copper thickness be controlled in software? This is the first time I’ve heard of it. Even if there are PCB manufacturers, they will not look at this project, because there is no routine operation like this. The thickness is not increased by software, and it is customized to the manu... Read More

HDI Board market conditions | YMSPCB

We live in the mobile Internet era, mobile phone communication, computer electronics on our impact is very big.HDI PCB is also a large field of application, HDI PCB itself to increase more demand. Compared with traditional multilayer board, HDI circuit board adopts lamination method, USES blind h... Read More

Drill holes for printed circuit boards | YMSPCB

Drill holes for printed circuit boards Corrosion of printed circuit board, only a semi-finished product, must be drilled brush flux and other processes. Printed circuit boards for some equipment often need to be silver-plated to improve reliability. The hole of printed circuit board determines th... Read More

Multi-layer printed circuit board composition | YMSPCB

In the case of a large number of interconnection and cross requirements, PCB circuit board to achieve a satisfactory performance, it must expand the board layer to more than two layers, so there is a multi-layer PCB; The original intention of multilayer PCB is to provide more freedom for wiring p...

Copper clad board and aluminum base board four major differences | YMSPCB

Overview of copper clad plate Copper clad plate — also known as substrate.The reinforcing material is soaked in resin, and one or both sides are covered with copper foil. It is the basic material of PCB, often called base material.When it is used in multilayer production, it is also called ... Read More

Copper plating process of PCB outer layer (PTH) | YMSPCB

Purpose of copper deposition: The resin and glass fiber on the non-conductor part of the hole wall are metallized to perform the subsequent copper plating process to complete the metal hole wall which is conductive enough for welding. PTH process: Grinding plate: Remove the drilling-out tip. Uppe... Read More

Application characteristics of aluminum base board | YMSPCB

Aluminum PCB by its own structure, with the following characteristics: thermal conductivity is very good, single-side bound copper, device can only be placed in the bound copper surface, can not open electrical wiring hole so can not be placed as a single panel jumper. In general, a patch device,... Read More

Gold, silver and copper in PCB | YMSPCB

Printed Circuit Board (PCB) is a kind of Printed Circuit Board, which is widely used in various electronic and related products. PCB, also known as PWB (Printed Wire Board), was once used more in Hong Kong and Japan, but is now less common (actually, PCB and PWB are different). In western countri... Read More

Why is the copper thickness in PCB an ounce | YMSPCB

Ounce is a unit of weight. Why is it used to indicate thickness in PCB? The first thing to note is that the ounce is itself a unit of weight. Ounces and grams (g) are converted to 1OZ ≈28.35g. In the PCB industry, 1OZ means the thickness of 1OZ of copper spread evenly over an area of 1 square foo... Read More
