Abstract
The invention relates to a punching and processing process of a plate edge copper-plated half-hole plate, which is characterized by comprising the steps that: a milling cutter is used for dividing a plate on a forming machine; a first set of mould is erected on the workbench surface of a punch press; kraft paper is used for trying to punch the depth of the first set of mould; materials are adjusted to be stripped downwards; a printed circuit to be divided is punched for the first time; a second set of mould is erected on the workbench surface of the punch press; the kraft paper is used for trying to punch the depth of the second set of mould; the materials are adjusted to be stripped upwards; the printed circuit which has been punched for the first time is punched for the second time; and consequently, the processing of the whole single plate is completed. The punching and processing process of the plate edge copper-plated half-hole plate improves the production efficiency while meeting the requirements on the plate side plated through hole (PTH) half-hole quality on the printed circuit board, so that the production and processing cost is effectively reduced.
Description
Technical field
The present invention relates to a kind of punch press that uses half hole stamp method for processing is carried out in the edges of boards copper facing hole (PTH) on the printed circuit board, belong to printed circuit board (PCB) stamp plate manufacture field.
Background technology
Along with consumption electronic product is lightening, integrated, the development trend of multifunction, its design to printed circuit board is also more and more diversified.On the printed circuit board (PCB) of consumer electronics series products such as mobile phone, number and bluetooth earphone in the design, more edges of boards PTH half hole design has appearred.
Edges of boards PTH half orifice plate cut type common process formula is designed to select for use the big or milling cutter littler than groove width with groove width etc. on the printed circuit board, walks the knife cutting type design along profile.
Edges of boards PTH half orifice plate cut type processing method does on the printed circuit board; After edges of boards PTH half orifice plate was made through pressing → boring → electroless plating → skin → graphic plating flow process, (CNC) processed to cut type, and the bakelite plate at the make-up machine work top gets out the shop bolt hole earlier; Strike shop bolt; Be enclosed within on the shop bolt by design lamination number, access cut type program to be processed, carry out cut type processing.
The defective that this kind processing method exists:
(1) edges of boards PTH half hole can not stop to stick up the copper phenomenon fully after the etching, still need spend manpower processing in a small amount and stick up copper;
(2) can go out fraction hole copper and pullled after the cutting, promptly lack the copper phenomenon, this is prone to cause, and to eat tin bad;
