Title: Manufacture of substrate for mounting electronic component
Inventor: TAKADA MASATOME
IPC: H05K3/28
Filed: 1989-06-06
Abstract: PURPOSE:To improve the workability of solder resist printing by using a plate having a larger mask than that of the plate previously adopted in proportion to an increase in the number of printing. CONSTITUTION:As the number of printing is repeated, a specified clearance is produced between an unprinted section 221 in the first time and an unprinted section 221 in the second time since a plate has a mask larger than that of the previous plate. Therefore, there is no need for printing a solder resist 22 on the unprinted section. Furthermore, there is no need for deviating the position of the mask in the printing after the second time in order to print, which improves the workability of the printing of the solder resist 22. Solder resist films 21 and 22 are hardened on all such occasions. When the film 22 is replaced with an expandable solder resist 23, it will be possible to obtain a substrate for installing an electronic component which has an excellent bonding property for resign encapsulation dam without any need for surface polishing.

Abstract: PURPOSE:To suppress a difference based on a target speed to a minimum by rising the mechanical resonance point of an accessor at a strike by reconfiguration and to execute one motion at a high speed by the reconfiguration by providing a means to lower a carriage to a lowermost part at a strike by the reconfiguration, and switches a feedback gain to a high value. CONSTITUTION:Reconfigulation causes lowering of an Y-carriage 12 to a lower most part by a control means 20 during one motion, and a feedback gain is increased to a further higher gain by means of a gain switching means 22. As noted above, since, through the rise of the mechanical resonance points of accessors 14-1 and 14-2 and the increase of a feedback gain, a difference based on a target speed can be suppressed to a low value as against the increase of torque and a friction factor during extrusion of a trouble accessor and a moving speed can be improved, the reconfiguration can rapidly complete one motion in a specified time.
