SEMICONDUCTOR FABRICATION APPARATUS AND SEMICONDUCTOR FABRICATION METHOD
A semiconductor fabrication apparatus has a transfer plate having a plurality of transfer pins to transfer a flux onto a plurality of lands on a semiconductor substrate, a holder movable with the transfer plate, to hold the transfer plate, a positioning mechanism to perform positioning of the holder so that the plurality of lands and the respective transfer pins contact each other; and a pitch adjuster to adjust a pitch of at least part of the plurality of transfer pins.
FLUX COATING DEVICE AND METHOD FOR SOLAR CELL PANEL, AND APPARATUS FOR ATTACHING INTERCONNECTOR OF SOLAR CELL PANEL
A flux coating device for a solar cell panel, can include a flux bath configured to receive flux and having an inlet and an outlet, in which the inlet and the outlet of the flux bath are configured to pass an interconnector below a surface of the flux, and the interconnector can include a wiring material including: a rounded portion or a circular cross-section, a core layer, and a solder layer formed on a surface of the core layer.
FLUX TRANSFER TOOL AND FLUX TRANSFER METHOD
A flux transfer tool includes a flux tray, a baseplate, a flux transfer head and a flexible member. The baseplate is disposed on the flux tray. The baseplate has a plurality of holes formed thereon. The flux transfer head is arranged corresponding to the flux tray and configured to move with respect to the flux tray. The flexible member is disposed on the flux transfer head. The flexible member faces the baseplate when the flux transfer head is located above the flux tray. When the holes are filled with a flux, the flux transfer head moves towards the flux tray, such that the flexible member adsorbs the flux from the holes.
Die attachment apparatus and method utilizing activated forming gas
A die attachment apparatus for attaching a semiconductor die onto a substrate having a metallic surface comprises a material dispensing station for dispensing a bonding material onto the substrate and a die attachment station for placing the semiconductor die onto the bonding material which has been dispensed onto the substrate. An activating gas generator positioned before the die attachment station introduces activated forming gas onto the substrate in order to reduce oxides on the substrate.
Flux applying device
A flux applying device for applying flux to a surface of solder, wherein the flux applying device includes: a dipping means that applies the flux to the surface of the solder by dipping the solder into the flux; a load applying means that applies a predetermined load to the solder, the load applying means being provided at a upstream side of the dipping means; a constant speed conveying means that conveys the solder at a predetermined speed with being under load by the load applying means; a drying means that dries the solder to which the flux is applied; a cooling means that cools the dried solder; a conveying speed measurement means that measures a conveying speed of the solder; and a control means that controls the conveying speed of the solder.
COMPONENT MOUNTING MACHINE
Component mounting machine includes head, a device for moving head, transfer unit, and a mounting controller. Circular plate is an example of a container in which paste is placed. The bottom face of circular plate and the upper surface of the side wall have a predetermined height relationship. Height sensor is disposed on the lower face of head. Height sensor measures the height of the upper surface of the side wall of circular plate, which is a measurement point. The mounting controller recognizes the height of the bottom face of circular plate or the height of the surface of coating film disposed on circular plate from the height of the top surface of the side wall of circular plate measured by height sensor.
FLUX TRANSFER METHOD
A flux transfer tool includes a frame, a plunger, a baseplate, a flux supplier and a driving mechanism. The frame has a chamber. The plunger is movably disposed in the chamber. The baseplate is mounted on the frame. The baseplate has a plurality of holes formed thereon. The flux supplier is connected to the frame and contains a flux. The flux supplier supplies the flux to the chamber between the plunger and the baseplate. The driving mechanism is disposed on the frame. The driving mechanism drives the plunger to move towards the baseplate to squeeze the flux out of the holes of the baseplate. The driving mechanism drives the plunger to move away from the baseplate to keep the flux in the chamber.
SELF-HEATING SOLDER FLUX MATERIAL
A self-heating solder flux material includes a solder flux material and a multi-compartment microcapsule. The solder flux material includes a solvent carrier, and the multi-compartment microcapsule includes a first compartment, a second compartment, and an isolating structure. The first compartment contains a first reactant, and the second compartment contains a second reactant. The isolating structure separates the first compartment from the second compartment. The isolating structure is adapted to rupture in response to a stimulus.

The first compartment contains a first reactant, and the second compartment contains a second reactant. The isolating structure separates the first compartment from the second compartment. The isolating structure is adapted to rupture in response to a stimulus. Rupture of the isolating structure results in an exothermic reaction between the first reactant and the second reactant. The exothermic reaction generates heat to volatilize the solvent carrier.
Method of printing solder paste
A method of printing solder paste on a substrate through minute apertures in a mask member, in which the solder paste is supplied to the apertures of the mask member under less than atmospheric pressure and has a viscosity so that the solder paste is filled in the apertures under atmospheric pressure. It is preferable that the solder paste has a viscosity of 50 through 150 Pa.Math.s and a thixotropic ratio of 0.3 through 0.5. Further, the solder paste is obtained by mixing a flux containing solvent having a boiling point such that volatilization thereof is suppressed under the less than atmospheric pressure and solder powders. It is preferable that in the flux, the solvent having the boiling point of 240 C. or more is used and the solvent is octanediol.
