Abstract: PURPOSE: To prevent the generation of a solder bridge which is easily generated, when a component of a terminal of narrow pitch is soldered. CONSTITUTION: An excess solder absorption region 24 which is not provided with a solder resist 20 is provided to a tip side of a terminal 14, rather than to an end part 22A of a solder pad 22 in the solder resist 20. If much solder paste is attached on the solder pad 22 when the terminal 14 is soldered, excess solder 28 which is fused by the heat of a heating heater travels through a terminal 14 and flows to the tip direction of the terminal 14, inside an excess solder- absorbing region 24. Since the excess solder 28 does not go over the solder resist 20 between the terminals 14, a solder bridge is not formed.

Abstract: PROBLEM TO BE SOLVED: To grip a chip by a head to solder keeping the molten solder by with molten. SOLUTION: Solder bumps 3 formed on a chip 1 face the electrodes 11 on a mounting board 10. Then the solder bumps 3 are heated to their melting points by heating a heating block 21 provided on the rear surface side of the chip 1. It is preferable to provide another heating block 22 on the rear surface of the board 10. With the solder bumps 3 molten, the bumps 3 are soldered to the electrodes 11 by bringing the bumps 3 into contact with the electrodes 11.

Abstract: PROBLEM TO BE SOLVED: To reduce variation of plate thickness of a TFT glass substrate (an array substrate) after polishing.
SOLUTION: On a corner part 4 where an X-edge 2 and a Y-edge 3 of the TFT glass substrate 1 intersect each other, a C-chamfering 5 as a chamfer with a specified dimension from an intersection 4a of X-, Y-edges is provided and polishing is carried out while a CF substrate 11 is laminated. By providing the C-chamfering 5, a polishing layer of a lower surface plate 609 is brought into contact with a full surface of the TFT glass substrate 1 with a uniform load. Thereby, when the TFT glass substrate 1 is polished with a polishing device 600, deformation of the corner part 4 generated by making a seal part a fulcrum is diminished. As a result, reduction of polishing amount on a single plate part 1a is prevented.
