摘要: In a hardening temperature profile of a paste material for fixing a lead-frame to a semiconductor chip, a heating temperature from a first sub-zone to a third sub-zone is set to 150.degree. C. and a heating temperature from a fourth sub-zone to a sixth sub-zone is set to a maximum value of 230.degree. C. at a first heating step of a chip fixing step. Then, in the hardening temperature profile, a heating temperature of a seventh sub-zone is set to 180.degree. C. having a drop width from the sixth sub-zone of 50 degrees and a heating temperature of an eighth sub-zone is set to 130.degree. C. having a drop width from the seventh sub-zone of 50 degrees at a second heating step of the chip fixing step.

摘要: A cover for a can comprising a multi-layer base of aluminum foil between heat-fusible resin layers and an overlying laminated resin layer. The outer resin layer has an inner section and a surrounding outer section separated by a gap through which the multi-layer base is exposed. The gap is smooth and continuous, that is, does not have a point, so that the inner section can be leveraged into the multi-layer base and the stress is uniformly distributed over a wide area of the multi-layer base.

摘要: A can comprising a barrel, an upper lid and a lower lid bonded to the barrel. Both the upper and lower lids comprise a gas liquid impermeable barrier layer, preferably aluminum foil, and resin layers heat fused to both sides thereof. Another resin layer is bonded to the exterior of the lids, with the upper lids having a tab and score to be perforated by the tab built into the resin layer. According to the invention, the yield strength of the top lid is made greater than that of the lower lid to prevent breaking of the score if the can is dropped. The differential strength may be accomplished by making the barrier layer of the top lid greater than that of the bottom lid.
