Company Advantages
1. A-TECH castellated holes pcb is the outcome of thermodynamics knowledge. Its whole body part especially the air circulation parts are made with special materials and circulating layout. The product can be resistant to corrosion
2. The product is available at an affordable price and is currently very popular in the market and is believed to be used more widely in the future. Being laminated by advanced vacuum lamination equipment, it has a uniform dielectric thickness after lamination
3. It has the advantage of quick heat transfer capacity. The thermal interface material is applied to the base of the product so as to fill gaps and offer more dissipation paths for the heat. The product is certified under UL(E357001) and RoHS
4. The product achieves a better heat dissipation effect. It is specially designed with a temperature higher than the surroundings to transfer heat by convection, radiation, and conduction. With a compact design, it is space-saving
5. It is highly resistant to chemical corrosion. It is electrostatically sprayed with the powder paint to form a thick layer which can protect the surface from corrosion. A smooth part is added on its PTH line to reduce the roughness of through hole


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.
