Title: Solder pre-coating method
Inventor: SAKAI TADAHIKO
IPC: H05K3/34
Filed: 1998-03-26
Abstract: PROBLEM TO BE SOLVED: To obtain a solder pre-coating method which can reduce the occurrence of a solder bridge and eliminate the need for cleaning after a solder pre-coating operation. SOLUTION: A pre-coating method applies solder paste 3 flat around electrodes 2 on a substrate 1, heats the substrate 1 so as to melt solder particles in the solder paste 3, and deposits the solder particles onto the electrodes 2, so that a solder pre-coating is completed. The volume ratio of the solder particles is 30% or less in the solder paste, and a liquid organic matter constituting the solder paste 3 can activate and is mainly composed of a volatile organic material, which disappears from the surface of the substrate 1 in a heating process. Therefore, it is possible to reduce the occurrence of a solder bridge, which is solidified as the electrodes 2 remains solder bridging, and to prevent residues of the organic matters from remaining after the solder pre-coating. Consequently, a cleaning operation is not necessary after the solder pre-coating.

Title: Abrasion-resistant flexible composite body and manufacture thereof
Inventor: JIYON EI ETSUFUENBAAGAA
IPC: D06N7/00
Filed: 1985-04-13
Abstract: Fluoropolymer containing coatings are applied to substrates, preferably textile substrates, to obtain composites which are flexible and not brittle, and which exhibit a low coefficient of friction, good wear resistance and excellent release properties. This invention comprises the technique of initially coating a flexible substrate, such as glass fabric or a metal mesh, with a fluoropolymer, which serves to prevent cracking upon flexing. The precoated substrate is thereafter coated with a blend of a hard polymer and a fluoropolymer which adheres well to the pre-coated intermediate substrate. Significantly, the composites of the invention are flexible, yet possess the wear resistance of the hard polymer component as well as the frictional and release characteristics of the fluoropolymer components.
