Specific implementation mode
Detailed explanation is made to invention content below in conjunction with the accompanying drawings.
Referring to FIG. 1, FIG. 2 and FIG. 3, the utility model includes the voltage dependent resistor chip 1 of cylinder or cuboid, described pressure-sensitive
A patch electrode is respectively set in about 1 the two poles of the earth of resistance chip, is welded in the patch electrode 2 of pole on the voltage dependent resistor chip 1
For wide belt flake, the welding ends with chip is at " Y " font.It is welded in the patch electrode 3 of 1 time pole of the voltage dependent resistor chip
Width for " convex " type, welding ends is less than connecting pin width.The patch electrode 2,3 is band-like " Z " font or " ［ " word of thin slice
Type or " " copper electrode of font, the copper electrode passes through electroplating processes.One end of the copper electrode is welded in the varistor
Chip 1, the other end are placed in the same side of the voltage dependent resistor chip 1, and with plastic casing in same plane, the varistor
Shell encapsulates the plastic casing 4 of squarely using plastic material injection molding process.
The utility model by the special copper electrode at " Z " font or " ［ " font or " ］ " font of the copper sheet of two strip shapes,
It is welded on the chip of varistor or more the two poles of the earth after plating, varistor plastic-injection is encapsulated into squarely.
Piezoresistor is molded by the utility model with plastic-injection for the first time, and is applied to small pieces using thin slice band electrode
On the piezoresistor of diameter mesohigh, realize mesohigh piezoresistor product Surface Mounting Technology, make related field production all from
Dynamicization improves production efficiency, reduces production cost.It is particularly suitable for the piezoresistor of small flake diameter.
Example the above is only the implementation of the present invention is not intended to limit the scope of the invention, every to utilize this hair
Equivalent structure or equivalent flow shift made by bright specification and accompanying drawing content is applied directly or indirectly in other relevant skills
Art field, is included within the scope of the present invention.
