The quality control of A-TECH vippo pcb is strictly conducted. This control procedure includes parts of a shoe and as well as materials. With a compact design, it is space-saving2.
The appearance of this product communicates intangible brand attributes. It lives up to the consumers' expectation of the brand promise. It is lead-free and environmental-friendly and has passed SGS test3.
The product has good washing shrinkage resistance. During the material treatment, its fabric has been sanforized by the machines, hence, the fabric will not shrink any longer. The inner layer core of the product is chemically treated for improved adhesion of the copper surface4.
The product is very resistant to scratches. Its anti-scratch coating acts as a protective layer which makes the countertop both more durable and safer. The product is certified under UL(E357001) and RoHS5.
The product has excellent mechanical strength and loading capacity. It is treated with die-casting under high-temperature and high-pressure conditions, therefore its structure is firm and tough.
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.
