A-TECH blind buried via and blind via durable for wholesale

Company Advantages
1. It is buried via and blind via that helps gain the popularity among the market. It has increased power densities which guarantee its long service life
2. This product is believed to have a wide application field. Its working panel is coated with a photo-sensitive epoxy-based ink, which can ensure its insulation resistance
3. The product is good in heat transfer. The thermal interface materials fill the air gaps which have low heat conductivity, therefore improving the heat conduction path. The inner layer core of the product is chemically treated for improved adhesion of the copper surface
4. The product is not easy to accumulate dust. Its fins are less likely to get heat which may generate electrostatic discharge which attracts air impurities due to electrostatic discharge. Its robust structure allows it to be used in harsh environments

The countersink is a kind of conical hole which drilled by special drill bits, it allows the tapered head of a screw to be inserted and screwed down in the hole to sit flush with the surface of the circuit board.

In order to ensure correct manufacturing for countersink design, PCB manufacturers require the details of the hole diameter or other specifications, the detailed information as below is needed:

● Countersink is drilled on top or bottom side?
● Countersink is copper plated or non-plated?
● The angle of countersink
● The finished diameter of countersink at the surface
● The depth of countersink
● The finished diameter of the shaft of the countersink

Drill bit with different angles are the key tools to make countersink, the angles with 82 degree and 90 degree are usually used in many kinds of design, but other angles like 60 degree, 100 degree, 110 degree, 120 degree and so on are also possible based on demands.

A-TECH is capable of building different types of countersink with different diameters and angles, and no matter copper plated or non-plated, welcome to send inquiry if you have related demands.
