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 cu...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 Board is also a large field of application, HDI Board itself to increase more demand. Compared with traditional multilayer board, HDI Board adopts laminati...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 c...Read more -
Multi-layer printed circuit board composition | YMSPCB
In the case of a large number of interconnection and cross requirements, printed 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 multi-layer PCB is to pr...Read more -
Copper clad board and aluminum base board four major differences | YMSPCB
Overview of copper clad board Copper clad board--- also known as base material. The stiffener 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 produ...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 ...Read more -
Application characteristics of aluminum base board | YMSPCB
Aluminum base board 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 it also can not be placed as a single ...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 diff...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 ov...Read more
