Title: Solder feeding method and manufacture of part mounting substrate
Inventor: NAKAI TOMOYUKI
IPC: H05K3/34
Filed: 1996-03-01
Abstract: PROBLEM TO BE SOLVED: To feed the necessary quantity of solder to necessary part by a method wherein the solder grains on the part where flux is not applied are removed by giving acceleration to a junction part. SOLUTION: Flux 3 is applied to a plurality of lands 2 on a circuit substrate 1, and solder powder is applied to the circuit substrate 1 by sprinkling from a solder powder feeding nozzle. The surface to which the solder powder 6 is applied is faced downward, and vibration is added to the circuit substrate 1 by a vibration load device 9. As a result, the solder powder 6 which is directly adhered to the flux 3 is retained to the circuit substrate 1 by the adhesive property of the flux 3, but the solder powder applied to the region where the flux 3 is not applied and the excessive solder powder thickly applied to the flux 3 are thrown off. As a result, the necessary quantity of the solder powder can be fed to the necessary part, and the quantity of solder powder to be discarded can be reduced.

Title: Lead frame for semiconductor device
Inventor: HIROTA MASAHIRO
IPC: H01L23/50
Filed: 1988-03-24
Abstract: PURPOSE:To prevent the displacement of the coining of bonding and an island, and to inhibit the breaking of a bonding wire by fixing a section near the coining of an inner lead by using an insulator. CONSTITUTION:Sections near the coinings 1a of inner leads 1 are connected and fastened by an insulator 3 such as fine ceramics or polyimide. Consequently, the displacement of the inner leads is suppressed on bonding, and distances among the coinings and an island, bonding pads for a chip, are kept constant. Accordingly, bonding wires are difficult to break, the torsion of lead themselves is prevented because the inner leads 1 are fixed, and thickness need not be thinned even when lead width is reduced.

Abstract: PURPOSE:To ensure that the generation of scratch is minimized and the settlement of dust is prevented from occurring by providing an organic protective film on the incident surface side of a photorecording medium using a laser beam and forming the organic protective film with a mixture of an acrylic material and a reaction activator having an electric charge preventing function using radiation-curing technique. CONSTITUTION:A photorecording medium consists of, for example, a substrate where a recording pit or a guide groove 1 is formed, a reflective film or a recording film 3 and an organic protective film 5. A laser beam is allowed to enter from the top of the substrate 2, then a reflected light from the reflective film of the substrate 2, then a reflected light from the reflective film or recording film 3 is received and this received light is converted to information by a light/electricity conversion element. The organic protective film 5 is formed by curing a mixture of an acrylic material and a reactive activator with an electric charge prevention function using radiation. The reactive activator with an electric charge prevention function is cured at the same time as when the acrylic material is cured by radiation. Further, part of the three-dimensional mesh structure of an acrylic protective film is carried by the reactive activator and these two become firmly bound together. In addition, the activator has an electric charge prevention function as it is prevented with an activation function. A surfactant of anionic, cationic, nonionic or dipolar type is used as the reaction activator.

Abstract: PURPOSE:To detect a frequency without the effect of offset amount by providing a comparator to compare the signal outputted from a subtracting device with a reference value and to convert it to a rectangular wave consisting of two level values. CONSTITUTION:By a phase difference branching filter 2 furnished with phase shifters 4 and 6, an inputted digital signal (a) is divided to signals K and I having the phase difference of 90 deg. and sent out to the subtracting device 8.

Next, the signal (m) is compared with zero volt by the comparator 10 and converted to the rectangular wave consisting of two level values. That is, when the signal (m) is higher than zero volt, it is sent out to an edge counter 12 as a signal (n) of the rectangular wave of +1, and the rectangular wave of -1 when the signal (m) is less than zero volt. After a reset signal is inputted, the edge of signal (n) is counted for one second by the edge counter 12 to send out the counted value to a dividing device 16 as a signal 0. The frequency of signal (a) obtained by dividing the counted value of signal 0 by 2 is outputted by the dividing device 16 as a signal P.
