Abstract: A method of blasting IC frames as electronic components with a suitable apparatus, which prevents the frames from being caught by position restriction means during transfer, and eleiminates necessity for particular operations even if frames of different widths are continuously fed.The blasting is carried out by turning a conveyor belt (8), which has support plate members (11) juxtaposed thereon and has a support groove (D) of an inverted triangular sectional shape formed thereon, jetting slurry onto the IC frames (F) merely placed on the slope surfaces inside the support support groove from a nozzles (2), turning then the frames by a reversion device (3) so as to place them on other slope surfaces, and jetting the slurry from other nozzles.

Abstract: The disclosure relates to a compact apparatus which effectively washes holes of printed circuit cards, flushes exfoliation off printed circuit cards and nameplates after etching, degreases and flushes number-plates before painting, and cleans iron, plastic, and glass plates, wherein a processing cistern is divided into a carry-in compartment (A), a cleaning compartment (B), a water-wash finishing compartment (C) and a drying compartment (D), the carry-in compartment (A) comprising an infeed roller, a pair of rubber rollers mounted vertically facing each other at a certain forward position thereof and a cleaning solution shut-out roller rotatable by the lower roller of the pair, the cleaning compartment (B) comprising a pair of rubber rollers vertically facing each other at a certain forward position of the pair of rubber rollers, a cleaning solution shut-out roller rotatable by the lower roller thereof, transfer rollers with conveying belts stretched therebetween so mounted that they may be rotated at the sam

Abstract: This printed circuit plate washing apparatus is used for effectively washing the openings of printed circuit plates, eliminating a cleaning water after etching printed circuit plates or nameplates, degreasing aluminum plates before printing and number plates before painting and washing iron, plastic or glass plates. For these purposes, said apparatus is divided into three sections (or chambers) such as a bring-in chamber, a washing chamber, and a wash-out/finishing chamber. Further, this washing line of said apparatus is so composed that a plate to be washed may be elevated in slope with a certain fixed angle for the level line from said bring-in chamber toward said wash-out/finishing chamber, thereby a washing water being overflown to said washing chamber and to said bring-in chamber in this order through respective partition plate. And a carrying means is provided in every chamber by means of belt, chain or wire net.
