Description
Technical field
The present invention relates to a kind of PCB industry production equipment, relate in particular to a kind of after pcb board spare boring the cleaning equipment of residue in the cleaning eye.
Background technology
PCB (Printed Circuit Board), Chinese is printed circuit board, claims again printed circuit board (PCB), printed substrate, is important electronic unit, is the supporter of electronic devices and components, is the supplier of electronic devices and components electrical connection.
In the PCB production process, need to hole to it, the hole of brill has plenty of in order to make via so that each layer of copper facing circuit has plenty of for making locating hole etc.
Pcb board spare 1 is through after the machine drilling, formation pcb board hole 6 has the part copper wire and the PP dust stockpiles in the hole, form the hole slag, the hole slag is mainly the various dust 8 (seeing Fig. 2) such as Copper Foil, copper wire, glass fibre and PP powder, stay great quality hidden danger for the plating production and processing of back, as electroplating without foreign material in metal, the hole in copper facing uneven thickness, the hole in the hole etc.Boring mud appears in a hole to be left over, and will cause whole product rejection, and the important quality problem in always manufacturing as PCB again without metal in the hole.Although once adopted other method (to be mainly chemical desmearing on the technique, being specially plate allows brill dirt and liquid medicine react in chemical medicinal liquid, through ultrasonic vibration, and then water cleans) solve, but use cost is high, and flow process is numerous and diverse, and product rejection also occupy the prostatitis that PCB manufactures always.
Simultaneously, if use some simple plant equipment to carry out copper ashes removing in the hole, can make some products not need to process through chemical medicinal liquid, reduce the cost in the manufacturing and shorten the manufacturing cycle, but effect be not satisfactory.
To this, someone proposes with high velocity air purge hole, to reach the purpose of cleaning eye slag.For example application (patent) number: 200720054228.4, the Chinese utility model patent of title " a kind of high-pressure blast knife hole block removing device " discloses a kind of high-pressure blast knife hole block removing device, comprise body, the substrate delivery wheel is installed in the described body, be provided with high pressure blast chamber in the described body, described substrate delivery wheel runs through this high pressure blast chamber, and high pressure blast indoor location has high-pressure blast knife, the air outlet of high-pressure blast knife is relative with the substrate delivery wheel, and the high pressure blast chamber second line of a couplet is connected to dust exhaust apparatus.
Although this equipment uses the hole on the pressure-air purge pcb board spare, but only utilize the malleation of air outlet to carry out purge, efficient is not high, although be provided with dust exhaust apparatus, but the air-flow that device produces is discharged after filtering by dust exhaust apparatus, so that whole air compartment is in the positive air pressure environment in the whole equipment, easily causes dust to leak, contaminated environment, and be not easy to reclaim.
