A-TECH half depth blind vias pcb Suppliers for wholesale

Company Advantages
1. This product is reliable, efficient, attractive, has flawless finishing and so many qualities. A smooth part is added on its PTH line to reduce the roughness of through hole
2. People will find that it is ok to turn this product on and off frequently and no problem will happen. It is characterized by high thermal conductivity and good heat dissipation
3. The product is not subject to the water. Its housing is well sealed and can be wiped with clean water without affecting the internal circuitry. Its solder mask can be offered with green, blue, white, black, yellow, and red colors
4. The dehydrating food preserves the natural nutrients that they contain. The simple water content removing process controlled by warm air circulation has no influence on its original ingredients. Being laminated by advanced vacuum lamination equipment, it has a uniform dielectric thickness after lamination

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.
