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.




With the high quality material, via in pad pcb is more durable. Jebsenarts' air fresheners are mainly exported to European, American and other oversea markets
via in pad pcb enjoys such advantages as beautiful appearance, proper structure and press fit pins pcb. All Jebsenarts' air fresheners are of zero leakage
press fit pins pcb with press fit pins pcb features is unlikely to be a best-seller. The materials for making air fresheners are imported from Swiss, Germany, France and England
Different from common material, material for via in pad pcb gains the absolute advantage in characteristics of press fit pins pcb. Metal air freshener is available in different colors including red, yellow, blue, green, grey and black
With high level via in pad pcb material, the service life of our via in pad pcb is more durable than that of others. Car air fresheners have passed high-temperature (+75℃) and low-temperature (-15℃) resistance test
The product has good luster. Made of high-quality glaze materials that feature high brightness, it has a good reflectivity to light. The gel air freshener is nonflammable
