PCB sub-board is a kind of sub-board equipment which is divided into PCB boards. It is an electronic equipment necessary for electronic manufacturers because PCB sub-board is used to cut the PCB board through the movement of the blades. It can be more effective. The stress generated during the control of the sub-board can prevent the damage and displacement of the components. It can have greater quality assurance than the sub-boards of the manual and cutting pliers. To buy the sub-board machine, you can go to Dongguan Chang'an to create a Weifen From the perspective of the board machine, more than ten years of experience in the development and production of the board machine.
The PCBA splitter is to separate PCBA boards together. It is a necessary equipment in PCBA processing plants.
1. Stable operating mechanism to prevent improper external force causing PCB solder surface, electronic parts solder joints, and other electrical circuits to be destroyed during the folding process.
2, special round knife material design to ensure the smoothness of the PCB split surface.
3, cutting stroke distance adopts touch-type five-section adjustment, can quickly switch different PCB
4, install high-frequency eye protection lighting device, improve the operator's job quality.
5. Strengthen safety devices to avoid human injuries.
6, simple cutting distance adjustment: easy to operate the cutting size adjustment contact button.
7, knife wheel pressure adjustment: use eccentric cam 0-2mm knife wheel clearance adjustment.
8, double-sided support design, so that the double-sided panel can be more firmly cut.
9. The rear panel design of the PC board and the upper and lower knife is vertical, effectively increasing
A. Steady when cutting B. PCB edge flatness C. Tool life.
10. Design of safety mechanisms for upper and lower knife guards, machine safety eye and emergency stop switch,
Second, the use of PCBA board machine The PCBA splitter is mainly used to separate the PCBA boards that are put together in the PCBA factory. After the PCBA is completed, the splitters are usually boarded and then tested. Generally, the board is not separated at the SMT chip processing plant, but the board is shipped directly to the customer.
In some small and medium-sized PCBA processing plants, manual board division will be used, but it is easy to damage the PCBA board and use the machine to perform the board separation.
(1) Single-side mixing, that is, placement of a patch element or an insert element on one side of the PCBA.
(2) Mounting on both sides, PCBA is placed on one or both sides.
(3) Double-side mixing, PCBA surface mount placement components and insertion components, and B surface placement of patch components suitable for wave soldering.
The selection principle for the standard PCBA sub-board substrate:
Appearance requirements: the appearance of the substrate should be smooth and flat, not warped or uneven, the substrate surface may not appear cracks, scars, rust and other defects.
