Filed: 1984-11-28
Abstract: PURPOSE:To reduce the manufacturing cost by making the outside of a pack material contacting to a punch larger than a metallic die side, and preventing the generation of wrinkles of the pack material by a restraint of the pack material. CONSTITUTION:A ring material 13 is attached to the outside periphery of an upper face pack material 6, and the outside diameter of the upper face pack material 6 is made larger than a metallic die side pack material 7. Also, a welding bellows 12 which can expand and contract in the thickness direction of a thick wall material is stuck to the upper and the lower pack materials 6, 7. When forming the thick wall material 5 through a punch, a tensile force of the radial direction works on the upper face pack material, an increase of a surface area by forming a recessed part all becomes an elongation, and the generation of wrinkles of the upper pack material 6 is prevented. Accordingly, a transfer of wrinkles to the thick wall material 5 is also eliminated, and an allowance of a plate thickness of the thick wall material 5 can be reduced. According to this method, the cost of material and the cost of working are reduced, and the manufacturing cost is reduced.

Abstract: PURPOSE:To prevent deviation of a leadless chip carrier(LCC) at the time of placing and to alleviate a solder short-circuit by using a printed board having a spot facing with a protrusion of a peripheral edge matched to an uneven part of the LCC in the same shape as that of the LCC. CONSTITUTION:A spot facing having a protrusion 2 of a board matched to the recess of an electrode of a solder connecting part of an LCC1 and engaged with the LCC1 is formed on a printed board 3. Then, the board 3 is soldered in a pattern matched to the electrode of the connecting part of the LCC1. Then, the LCC1 in which solder is previously adhered by a solder dipping method is inserted to the spot facing of the board 3, connected by a solder reflowing method, and the LCC1 is placed on the board 3. In this case, a large deviation of the LCC1 from the board 3 is suppressed by the spot facing, and small deviation is absorbed by a self-alignment effect at the time of solder reflowing with the plated solder 4 to the board 3 and spare solder 5 of the LCC1, and hence correction is almost eliminated.
