Technical Field

The utility model belongs to the field of PCBA production and processing, and particularly relates to a PCBA dust removing device.

Background

PCBA is an acronym for printed circuit board assembly (Printed Circuit Board Assembly). PCBA is a critical step in the manufacture of electronic products. It involves assembling the finished PCB with other components into a final complete circuit board.

PCBA divides the board to mean in order to adapt to market demand better and improve production efficiency, and electronic manufacturing enterprises have adopted PCBA to divide the board technique to improve PCBA manufacturing efficiency and reduce manufacturing cost. The board separation technology can enable different circuit boards on the same PCBA to be divided into a plurality of small circuit boards, so that the plurality of PCBA can be manufactured simultaneously, the manufacturing period is shortened, and the rejection rate is reduced.

When the board separating equipment cuts the connecting ribs in the PCBA board at high speed, dust and scraps can be generated, and although the equipment is provided with an exhaust device, the problem of the surface of the PCBA is still unavoidable due to the fact that a little scraps remain. Because of the stricter specification requirements (< 0.5 mm) for PCBA trim residues in the automotive electronics manufacturing industry, both on-line and off-line dispensing equipment are plagued with this problem.

Under the existing conditions, most production workshops mostly adopt manual hand-held blowing type air guns to clean PCBA, dust or scraps collecting devices are not arranged, dust or scraps can spread to the surrounding environment and can fall onto the surface of the PCBA again; and the production beat is long and the efficiency is low.
