Title: Method of treating printed circuit board
Inventor: UIRIAMU MOORISU MOOGAN
IPC: H05K3/34
Filed: 1989-10-06
Abstract: PURPOSE: To form a cover coating without performing alignment by simultaneously forming a pattern for conductor layout and a pattern for the cover coating by exposing a photoresist one time through a mask. CONSTITUTION: After an appropriately patterned mask 14 has been formed, a base layer material 11 coated with a thin copper foil 12 on at least one surface and a board having an upper photoresist layer 13 are exposed through the mask 14. The photoresist is applied as a dispersion and dried before being exposed. The exposed part is removed completely by selectively cleaning the exposed circuit board with a moderate developing agent. After the exposed part has been removed, an exposed copper area 15 is removed by etching a circuit and a resist 16 is removed with a stronger developing agent. Then a cover coat is blanket screen-printed on the circuit board in the form of a photosensitive agent 17 and blanket-exposed after drying. Consequently, the property of a part 18, which is in contact with the photoresist, changes and selectively dissolves together with the positive photoresist, leaving a cover coated area 19 and bare pads 20.
