s1: movably sleeving a chip 23 and a chip connecting column 24 in the protective box body 20, wherein auxiliary extrusion plates 22 arranged in the protective box body 20 are respectively contacted with the upper part and the lower part of the chip 23;

s2: placing a protection box body 20 in the lower template 10 with a groove on the upper part, placing, movably sleeving and sleeving a middle auxiliary template 12 on the upper part of the lower template 10, placing another protection box body 20, and movably sleeving and sleeving an upper template 11 on the upper part of the middle auxiliary template 12;

s3: adding sealing glue between the connecting parts of the lower template 10 and the upper template 11, and driving an extrusion device to perform press-fit limitation on the lower template 10 and the upper template 11;

s4: installing a first jacket 13, a second jacket 14 and a third jacket 15 outside the inner part between an upper template 11 and a lower template 10, movably sleeving the first jacket 13 and the second jacket 14 through the third jacket 15, penetrating a first fastening bolt 16 through the third jacket 15, fixedly sleeving the first jacket 14 in a threaded manner, sleeving a second positioning device jacket 18, a second fastening bolt 19 and a first positioning device jacket 17 in a sleeved manner, movably sleeving a second fastening bolt 19 in the inner part of the upper part of the second positioning device jacket 18, rotating the second fastening bolt 19, and driving the second fastening bolt 19 to be fixedly sleeved in the first positioning device jacket 17 in a threaded manner;

s5: cup joint the lower bolster 10 activity in the inside of supporting base 1 and supporting base two 3 to drive the inside that first 8 of extrusion splice plate and two 9 of extrusion splice plate passed lower bolster 10 and cope match-plate pattern 11, and extend to the inside of side location backup pad two 5 and upside connecting plate 7, start the extrusion device simultaneously, drive extrusion splice plate 8 and compress downwards, drive the inside of flexible regulating plate 6 activity cup joint in side location stripper plate 4 simultaneously, so far drive the device and stereotype.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
