Castellation pcbs

Castellation pcb is also known as castellated hole pcb or plated half holes pcb, which rows of holes are routed on the edges of the pcb and only a half of each plated hole remains in the PCB. PCBs with castellated holes are used to solder one PCB directly to another PCB or insert special design edge connectors.

Castellated holes pcbs are becoming more important especially with the rapid development of high-tech industry. Plated half-holes are mainly used board-on-board connections and can be applied in many applications.

Advantages of Using Castellated Holes
Castellated holes are a type of plated through-hole used in printed circuit boards that have been cut in half. They offer
several advantages over regular through-holes, including:
I)Using castellated holes can help designer validate the quality of the solder joint.
II)Castellated holes are also helpful, especially for breakout boards and small modules such as Wi-Fi modules.
III)These plated half holes can easily change the pin layout of the component according to different requirement of each user.
IV)PCBs with castellated holes can easily mount one pcb to another PCB boards during production.
V)Castellated holes also help to create wireless PCB to PCB links.
