4 Layer ENIG FR4 Half Hole PCB
Half Hole PCB
Mainly used for on-board contact, using electroplated half-hole PCBs or castle holes, usually used when two printed circuit boards are mixed using various technologies. For example, complex modules of microcontrollers and typical single PCB configurations.
Further implementations are displays, HF or concrete modules welded to the base circuit board.
Therefore, the onboard PCB is required as a half coating for SMD connection pads. By connecting PCBS directly together, it is much thinner than similar links with multi-pin attachments.
Pros And Cons Of Half Hole PCB
High density, multifunction and mechanization become the standard of exponential growth of electronic equipment in the future. The board is developed with geometric indicators, but the PCB size is getting smaller and smaller and must be related to the support board. Since the round hole is poured into the motherboard with solder flow, cold welding will occur, resulting in a weak electrical connection between the circuit board and the motherboard, because the round hole is large, because there is an electroplated PCB half hole.
Pros:
- Easier to use prototypes
- Huge defensive links
- Resistance to heat
- Capacity to handle power
Cons:
- Increased board costs due to boiling
- Occupies more real estate board
- PCB assembly involves more
- Higher velocities
Applications Of Half Hole PCB
Metallized half hole PCBs are commonly used in telecommunications, computing, automotive, gas and high-end technology fields.
