Product Information of routing impedance control pcb durable at discount
Company Advantages
1. A-TECH impedance control pcb is designed to be operated in a high efficiency manner. It totally conforms to the UL Flame Rating of 94V-0
2. A-TECH CIRCUITS Co., Ltd. has successfully developed a good business relationship with our customers and each day we continue to expand our customer base. It has increased power densities which guarantee its long service life
3. The product can withstand a wide range of temperatures. Its shape and texture will not easily be changed by the temperatures thanks to its natural properties. Being laminated by advanced vacuum lamination equipment, it has a uniform dielectric thickness after lamination
4. The product has a low self-discharge rate. It is not easily affected by the inner or outer temperature, and its chemical components keep stably under low or high temperature. It is lead-free and environmental-friendly and has passed SGS test


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.
