| Number | Title | Issue Date |
| 6156462 | Photosensitive resin compositions, cured films thereof, and circuit substrates For instance, when a washing-free yet low-residue type of flux is coated on a solder resist film, soldering can be carried out while no solder balls remain on a circuit substrate. A photosensitive resin composition comprises a photopolymerizable and photo... | 12/05/2000 |
| 5863355 | Flux for soldering electronic components on circuit substrates, and mounted or unmounted circuit substrate The invention provides a soldering flux for mounting circuit substrates, which is free from any organic solvent attributable to air pollution and dispenses with any washing step. The soldering flux is obtained by dissolving a rosin modified by an unsatura... | 01/26/1999 |
| 5853957 | Photosensitive resin compositions, cured films thereof, and circuit boards For instance, when a washing-free yet low-residue type of flux is coated on a solder resist film, soldering can be carried out while no solder balls remain on a circuit substrate. A photosensitive resin composition comprises a photopolymerizable and photo... | 12/29/1998 |
