Title: Repair and correction process for circuit boards - uses material coatings applied separately by metering heads
Inventor: KOHLER GERD DIPL ING
IPC: H05K3/12
Filed: 1992-11-09
Abstract: In a process for repairing or correcting the wiring of a circuit board and/or the electronic components mounted on it, the materials for producing the insulating and conducting paths are applied to the circuit board in separate operations. Materials are applied to the circuit board by metering heads which do not contact the circuit board. Both insulating and conducting layers are sprayed on at a width and thickness appropriate to their function. Nozzles in the metering heads work on the Piezo principle. The circuit board is held in a clamp during application of the coatings. An insulating layer is sprayed on first along a given path from the initial contact to the target contact. After polymerisation of the insulating layer(s), conductive paths are sprayed along the same path. The path coordinates can be followed by either: (i) moving the nozzle; or (ii) moving the circuit board. Polymerisation of the insulating layer is accelerated, e.g. by laser, IR light, hot air or oven heating. USE/ADVANTAGE - Correction and repair of the wiring of electronic circuit boards and/or components. Can be automated and is inexpensive.
