Abstract: PURPOSE:To provide a nickel or nickel alloy coating film remover, which can be used over a long period and with which side attack, etc., on the copper circuit of a printed circuit board can be prevented from occurring, by blending the remover contg. nitric acid and hydrogen peroxide with an alcohol compound. CONSTITUTION:The Ni or Ni alloy coating film remover comprises nitric acid, hydrogen peroxide and an alcohol compound. By using this remover, the decrease in the stripping rate is very small even when the concn. of the dissolved metals in the remover is increased by using the remover over a long period and therefore the remover can be used over a long period without increasing concn. of the oxidizing agent and/or acid and further, the problems such as side attack, side etching on the copper circuit of the printed circuit board can be prevented from occurring. Preferably, the amount of nitric acid to be added to the remover is about 10 to 700g/l as 62% nitric acid and the amount of hydrogen peroxide to be added to the remover is 10 to 200ml/l as 35% hydrogen peroxide. As the alcohol compound, one having 1 to 8 total carbon atoms can be appropriately used, preferably in an amount to be added to the remover of 0.1 to 200g/l.

Abstract: PROBLEM TO BE SOLVED: To mold a case into a predetermined dimension without any variation in shape of an opening and secure sufficient pressure resistance and leakage resistance by annealing the opening of the case, enlarging the opening, and forming a step on the enlarged portion. SOLUTION: An opening of a square metal case 1 of cold rolled steel (having a tickness 0.4mm) is annealed at 450-600 deg.C by a high frequency induction heater. Subsequently, the opening is enlarged by drawing, thereby forming an enlarged portion 1b. The enlarged portion 1b is subjected to ironing, thereby forming a step 1a and a drum 1c. Thereafter, a sealant is thinly applied to the inner face of the enlarged portion 1b. A sealing plate 3 having a terminal cap 3a welded at the center thereof is disposed on the step 1a through the enlarged portion 1b of the case 1 inside an L-shaped insulating gasket 2. The enlarged portion 1b is contracted, and an end of the opening is bent inward, to be thus sealed.  Consequently, the case can be molded into a predetermined dimension without any variation in shape of the opening, and sufficient pressure resistance and leakage resistance can be secured even if the sealing plate is caulked or fixed.
