Title: Film carrier tape for mounting electronic parts
Inventor: ISHIZAKA MASAHARU
IPC: H01L23/12
Filed: 1998-06-01
Abstract: PROBLEM TO BE SOLVED: To make short circuits hardly occur when inner leads arranged at a specific pitch are bonded to bump electrodes, by distributing electrolytic copper foil having specific average surface roughness, and forming plated-tin layers on the bonding surfaces of the inner leads to the bump electrodes. SOLUTION: The arranging pitch PO of inner leads 15 formed on a film carrier tape for mounting electronic parts by using electrolytic copper foil as it is without regulating its shiny surface having average surface roughness RZ of <3.5 μm falls within the range of 30-60 μm and plated-tin layers 31 are formed on the surfaces of the leads 15. Since the non-regulated surface of electrolytic copper foil having average surface roughness of <3.5 μm is used as the bonding surfaces of the leads 15 to bump electrodes 25, the strengths of the leads 15 can be increased and the occurrence of such a case that an excessive amount of gold-tin eutectic alloy 33 is produced and supplied can be prevented when the leads 15 are bonded to the electrodes 25.  In addition, the leads 15 are surely bonded to the bottom sections of the electrodes 25 and short circuits hardly occur though the leads 15 are arranged at a fine pitch.

Title: Treatment of volatile acids
Inventor: FURUYA CHOICHI
IPC: B01D61/24
Filed: 1988-06-20
Abstract: PURPOSE:To simply and effectively perform treatment by guiding a volatile acid and/or volatile gas into an absorbing liquid through a hydrophobic membrane and applying either one or more kind of neutralization, separation and recovery treatments thereto. CONSTITUTION:A solution containing hydrochloric acid is passed through a central space as a volatile acid-containing liquid 5 and an aqueous alkali hydroxide solution is passed through the space separated from said central space by a hydrophobic membrane as an absorbing liquid 7. Whereupon, hydrochloric acid in the volatile acid-containing liquid 5 is passed through the hydrophobic membrane 1 as hydrogen chloride gas or vapor to move to the absorbing liquid 7 and reacted with alkali hydroxide to be neutralized. Since the hydrogen chloride gas or vapor moved at this time is generated on the basis of the difference between the vapor pressure of the volatile acid-containing liquid 5 and that of the absorbing liquid 7, the hydrogen chloride gas or vapor can be moved by lowering the vapor pressure on the side of the absorbing liquid 7. For example, this purpose can be achieved by keeping the absorbing liquid 7 alkaline.

Filed: 1987-06-18
Abstract: PURPOSE:To realize compatibility between high speed property and a small hardware quantity, by using a specific symbol on a result in which the output of a memory where a degree calculated result is stored is multiplied by a fixed coefficient. CONSTITUTION:The symbol in which an even-th bit from the low-order of a binary vector is 0 and an odd-th bit from the low-order is 1 is used as a multiplicand for the result in which a memory output where respective degree calculated result from oth-order to (t)th-order of an error position polinomial is stored is multiplied by the fixed coefficients from alpha<o> to alpha<t> respectively. In such a way, a bit component corresponding to the even square of (alpha) out of the outputs of fixed coefficient multiplier groups 1-8 goes to 0, and the exclusive OR of the multiplied result of only the fixed multiplier of odd square of (alpha) is taken, and it is possible to find a result X.sigma (X) that is the result obtained by substituting an error position in the polynomial where the error position polynomial is differentiated easily without performing specific calculation.

Abstract: PURPOSE:To machine a highly accurate electrode for minute hole machining efficiently and easily by forming a machining electrode by means of electric discharge machining through a machining electrode and an electrode forming block, and forming a metallic film on the machining electrode by means of electrolysis or without electrolysis. CONSTITUTION:When a machining electrode 1 is overly scraped off by the removing operation of an electric discharge machining, the operation of the electric discharge machining is stopped. And, by moving a moving stage 4, etc., a second container 10 is placed below the machining electrode 1 and the machining electrode 1 is inserted into the electrolyte 11 in the container 10 through a driving means 3. In this condition, a selection changeover switch 15 is connected to input a power source 14. Thereby, an opposite electrode 12 is dissolved out as a positive ion into the electrolyte 11 and the dissolved metal is deposited on the machining electrode 1 with the lapse of time to form a metallic film 16, i.e., a plated film. Since the thickness of the metallic film at this time can be optionally set by controlling the conditions of the temperature of the electrolyte 11 and the voltage of the power source 14, a machining electrode 1 with an optional diameter can be formed.
