A-TECH plating thermal vias in pcb Suppliers top supplier

Company Advantages
1. The design of A-TECH press fit pins pcb is the outcome of a professional thermal solution. Influencing factors such as air velocity, choice of dissipation materials, and finish are taken into consideration by the designers. It has increased power densities which guarantee its long service life
2. The use of this product helps reduce operating costs. With its advanced operation system, it helps reduce labor costs and energy consumption. It is widely used in different electronics industries, such as telecommunication and consumer electronics
3. The product features dimensional stability. It can maintain its original dimensions when subjected to changes in temperature and humidity. Thanks to the up-to-date vacuum DES line, it is manufactured with fine traces and high density
4. The product is not easy to crack or fracture. There is extra material called the lasting margin is used to enhance the stickiness of its trims or edges. It is lead-free and environmental-friendly and has passed SGS test
5. The product has a reliable electrical system. It will auto stop working when open circuit, short circuit, and electric leakage occurs. It has passed AOI which ensures there will be no errors or welding defects

Plated half holes which is also called castellated holes, they’re normally designed at the edge of printed circuit boards and plated with copper, and they’re mainly used for board-on board connections, mostly where two circuit boards with different technologies are combined.

Most of the plated half hole PCBs are a type of modules which are small and high density with fine pitch components, this type of circuit boards are made with GPS Modules, Wifi Modules, Bluetooth Modules, GMS Modules, GPRS Modules and other smart modules.

Basically plated half holes are not suitable for V-score process, because the copper at the hole will be rolled up to cause serious burs, routing process is a better solution to ensure smooth edge.

The guidelines of designing plated half holes

● Normally the minimum half hole size is 0.8mm, it can be min 0.55mm with A-TECH capability
● The routing tolerance for half hole is +/-0.15mm
● The minimum distance from pad to pad is 0.25mm
● Use the larger hole diameter if possible
● Use the larger outer layer pad on both sides if possible
● Connect inner layer pads to the plated holes if possible to bring more stability and help to avoid burrs.
● Routing process is preferred and ENIG finish is preferred.

A-TECH have manufactured a large number of printed circuit boards with half hole design for various module products, and we have obtained rich experience to control high quality, the minimum half hole size we can build is 0.55mm.
