Description
Technical field
The present invention relates to the contour processing method that a kind of use throw forms the profile of workpiece (for example printed base plate).
Background technology
During processing printed substrate, under the state of the bigger printed base plate that contains a plurality of printed base plates (below title base plate product) (below title mother substrate) as goods, carried out the plating processing after perforation processing and the punching, afterwards, base plate product has been cut out from mother substrate (sharp processing).Like this, just can shorten step time in the electroplating work procedure after perforation processing operation and the perforation processing.
In order to improve the reliability of base plate product, by being configured in the dust collect plant of instrument periphery, the cutting powder that produces during with perforation processing and during sharp processing is removed (patent documentation 1) from adding Ministry of worker's periphery.
For multilayer printed board,, form through hole (through hole), and,, be electrically connected at the inner electrodeposited coating that forms of through hole by carrying out electroplating processes when to being configured in insulant graph layer up and down when being electrically connected.
The vertical view of the base plate product when Fig. 2 is sharp processing in the past, the arrow T among the figure represents the direction of rotation of throw, arrow C is represented cutting direction (moving direction of throw).
On the periphery (profile) of the base plate product 2 that from mother substrate 3, cuts out, be equipped with the through hole 1 (being illustrated as semi-circular shape) that is opening in periphery.When the throw of using with sharp processing (adopts the instrument of diameter 1～2mm mostly, is called ' milling cutter 5 ' router bit below.) when the through hole 1 that is formed with electrodeposited coating 4 is cut, then mostly situation be the part of electrodeposited coating 4 can be peeled off (below, the electrodeposited coating that has claimed to be peeled off for ' flash 6 ').Being connected between the electrodeposited coating 4 of flash 6 and through hole 1 end is unstable.So a lot of parts of flash 6 are siphoned away by dust collect plant in process, but some still links to each other with electrodeposited coating 4 after processing.Because flash 6 has electric conductivity,, then can occur causing the problem that is short-circuited between the terminal of base plate product 2 because of the flash 6 that comes off so flash 6 is in case split away off from base plate product 2 for a certain reason sometimes.Flash 6 is to be created in milling cutter 5 to enter into the cross part of a side (passing through side) of through hole 1 from substrate-side, and can not be created in the cross part place that is entered into a side of substrate-side by through hole 1.What therefore, carried out is so-called upset processing in the past.
Figure 3 shows that the processing sequence figure of upset processing.
Shown in figure (a), at first, processing is with respect to the base plate product 2 profiles (face of representing with chain-dotted line among the figure vertical with paper.Be called below ' polished surface S ') and side-play amount is the face (below be called roughing face F) of g.In addition, when processing roughing face F, the part of base plate product 2 also is connected with mother substrate 3, when mother substrate 3 table turning ins are changeed, does not allow base plate product 2 separate from mother substrate 3.
Then, shown in figure (b), mother substrate 3 table turning ins are changeed, and make the moving direction of milling cutter 5 process polished surface S in the same manner.In case the mother substrate 3 that is formed with roughing face F is shown turning in to be changeed, because milling cutter 5 is configured in a side that is entered into substrate-side by through hole 1, so shown in figure (c), 6 of the flashes that is produced in the roughing can be removed from substrate 2 when forming polished surface S.When accurately machined occasion, though being created in milling cutter 5 sometimes, flash 6 enters into a side of through hole 1 by base plate product 2 sides, (for example, 0.05mm), the size of the flash 6 of Chan Shenging will become small like this as long as reduce side-play amount g.Therefore, i.e. the flash 6 of toilet generation splits away off from base plate product 2, also can reduce the reliability as the goods of base plate product 2 hardly.
In addition, though here to milling cutter 5 for the situation of right rotation (just changeing) usefulness is described,, even if milling cutter 5 are anticlockwises (counter-rotating) with in, the position that flash 6 is produced also can be that milling cutter 5 is by the side of mother substrate 3 by through hole 1.
