Description
Technical Field
The invention belongs to the field of parallel seam welding mold design, and particularly relates to a packaging mold and a program design for a left-right symmetrical convex polygonal tube shell with an irregular rectangle and an even number of sides.
Background
The parallel seam welding technology is mainly applied to packaging integrated circuit chips, and the principle of the parallel seam welding technology is resistance welding. As shown in figure 1, two conical electrode wheels are utilized to press a cover plate to be packaged and a metal packaging edge on a tube shell, two high-frequency large currents start from the electrode wheel at one end and return to the other end through the cover plate and the tube shell, the high resistance of the whole loop is at the joint of the cover plate and the tube shell, the heat provided by the high-frequency large currents melts the joint, and a welding spot is formed after solidification. And setting the program to enable the welding spots to be continuously overlapped to form the welding seam.
The parallel seam welding technology has higher reliability than energy storage welding and laser welding, and has stronger sealing performance, low cost and high efficiency. The packaging is the last procedure of the assembly of the thick film hybrid integrated circuit, and the reliability of the tube shell is directly influenced by the quality of the packaging. The integrated circuit package provides a reliable and stable working environment for the circuit tube core in the tube shell, and plays a mechanical or environmental protection role for the internal components, thereby enabling the integrated circuit to normally play the function.
The device to be packaged can be heated and vacuumized in the packaging process, so that the content of water vapor and oxygen in the tube shell can be reduced, the chip is not easy to oxidize, and the chip is protected. High-purity nitrogen can be filled into the glove box, and the content of water vapor and oxygen in the pipe shell is further reduced. The operation process is set by a program, and all mechanical automation is realized except for cover plate alignment and tube shell placement, so that the burden of operators is reduced, and the packaging stability and consistency are improved.
The encapsulation procedure of the parallel seam welder can easily realize the encapsulation of the tube shells of a right-angled rectangle, a rounded rectangle and a round shape. When the rectangular tube shell is packaged, two sides of the rectangular tube shell are packaged, then the shell is rotated by 90 degrees, and the other two sides in the vertical direction are packaged; the circular shell needs to rotate the worktable 180 degrees along the Z axis to complete the packaging of the whole tube shell.
Most tube encapsulation needs special mould, and the factor that the mould design need be considered has tube height, shape and leg guiding position, and the mould of design can be with tube central point location at encapsulation mesa zero point position, effectual restriction X, Y direction degree of freedom, and Z axle direction height need rationally be in order to cooperate the electrode wheel height of pushing down.
