Further technical scheme is：It is characterized in that：The wire is copper cash.
Further technical scheme is：The body also includes spindle nose, and body is screwed with spindle nose and is connected.
Using above-mentioned technical proposal produce beneficial effect be：1st, temperature change is soft, and temperature is compiled via copper pipe and copper
Knitmesh is sent to the glue surface of pressing wheel again, it is to avoid the rising sharply and rapid drawdown of pressing wheel hull-skin temperature so that pressing wheel glue surface is each
Less, uniformity of temperature profile does not result in the phenomenon that press mold thickness differs to the temperature difference of point；2nd, temperature stabilization, temperature change receives ring
Border air impact is small, and gradient of temperature change is slow, is greatly decreased and causes minute bubbles phenomenon；3rd, the non-defective unit of production circuit board is greatly improved
Rate, it is cost-effective；4th, copper pipe and copper mesh grid are set using through through hole, improve security, be conveniently replaceable.
