Title: Method of fabricating soldering pads and bonding pads on thin-film hybrid circuits
Inventor: KROKOSZINSKI HANS-JOACHIM DIPL
IPC: H05K3/28
Filed: 1987-02-13
Abstract: In a single fabrication process, this method simultaneously produces both Cu/Sn soldering pads which are ideal for soldering surface-mounted components and Ni/Au bonding pads which are ideal for Al wire bonding. For this purpose, a glass layer (6) based on SiO2 is additionally vapour-deposited on the copper layers (5) provided for soldering. An Al2O3 layer (7) is then vapour-deposited on the entire circuit and coated with a photosensitive polyimide resist or a photoresist (8) which is exposed above the soldering pads (13) and the bonding pads (12) and developed. After etching the Al2O3 layer (7) in the pad windows, the copper layer (5) of the bonding pads (12) which is laid bare can be electrolessly plated with nickel and gold after activation with a Pd activator solution. After etching the glass layer (6) on the soldering pads (13), the copper layer (5) of the soldering pads (13) which is laid bare is electrolessly nickel-plated. <IMAGE>

Patent DE-3718806-A1 (DE)
Title: Marking apparatus
Inventor: TENZLER THOMAS
IPC: B42D5/04
Filed: 1987-06-05
Abstract: Marking apparatuses for printed matter, for example calendars, are known. In one form of such apparatuses, a tape-like strip of plastic material is held by means of a rubber band on the reverse of the calendar. In this case, the substantial assembly effort is especially disadvantageous, because each marking apparatus has to be mounted individually. In order to avoid this, the marking apparatus is to be of simpler construction than hitherto and to have more versatile possibilities in application. A carrier strip forms, at each of its two free ends, an open loop with the aid of which the carrier strip is fixed by frictional connection to the printed matter. The free ends ensure the frictional connection with the printed matter by prestress. A slide may also run on the carrier. <IMAGE>

Patent DE-3816971-A1 (DE)
Inventor: ARAMAKI MINORU
IPC: C08L27/12
Filed: 1988-05-18
Abstract: A fluororesin dispersion excellent in uniformity and stability is obtained by dispersing a powder, which is smaller than 2  mu m in mean particle size, of a fluororesin lower than 10000 in molecular weight in an organic liquid. No surfactant needs to be used in this dispersion. It is best to use an organic liquid relatively low in surface tension, such as trichlorotrifluoro- ethane, n-heptane or n-hexane. A typical example of the fluororesin is polytetrafluoroethylene. It is preferred to use a fluororesin powder not higher than 2000 in molecular weight and not larger than 1  mu m in mean particle size, which can be obtained by heating a higher molecular weight fluororesin in the presence of fluorine and cooling the reaction gas to cause precipitation of the molecular weight reduced and vaporized fluororesin.

Abstract: The invention relates to a process and device for the recovery of excess powder from powder coating booths (10). The excess powder is sucked out of the booths via cyclones (14) by means of ventilators, an acceleration section (16) being provided between the respective booths (10) and the cyclones (14), in which section the powder is accelerated so that it flows into the cyclones (14) at a sufficiently high flow speed, as a result of which the degree of precipitation efficiency is raised. The acceleration section can have a sieve (24) connected in front of it in order to sieve the powder and separate out foreign bodies and particles of dirt at an early stage. The cyclones (14) can be operated alternately so that one cyclone (14) is emptied whilst the other carries on running and vice versa without the operation of the powder coating booth (10) having to be interrupted. On the floor (34) of the booth a narrow-mesh web (36) is installed at an angle, to which air is fed from below, as a result of which powder which drops in the booth (10) and falls to the floor, is loosened up and carried out at the foot end of the booth. In order to remove very fine dust from the exhaust air, a tape filter is connected downstream of the ventilator, from which tape filter the powder deposited on it can be sucked off by means of a vacuum cleaner. <IMAGE>
