Some imported materials are used for A-TECH circuit board assembly
manufacturing. With a compact design, it is space-saving2.
It will balance the sleepers' temperature so well that they don’t wake up all hot and sweaty, and they never feel like they are too cold at night. Thanks to the up-to-date vacuum DES line, it is manufactured with fine traces and high density3.
This product has been certified by an authoritative third party, including performance, durability and reliability. The product can be resistant to corrosion4.
The product emits light in a specific direction, reducing the need for reflectors and diffusers that can trap light. It is lead-free and environmental-friendly and has passed SGS test5.
The product is in compliance with international industry quality standards. It is vacuum-sealed, which can greatly reduce the bulk of the overall cargo
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.
