摘要： When an alkaline earth metal carbonate powder is mixed with an adhesive and is formed into an adhesive layer in a conventional covering method, a problem of the transfer of catalyst for electroless plating during a masking step or later electroless plating step is solved. Further, blisters under plated film caused by a fire retardant contained in an insulating substrate is also overcome by the use of alkaline earth metal powder.

摘要： A process for producing a printed circuit board which comprises forming a plating film forming adhesive layer on the whole exposed surface of an insulating board, roughening said adhesive layer surface, depositing a catalyst for electroless copper plating on said adhesive layer surface from a catalyst solution, masking the thus treated insulating board surface excepting the part where a circuit is to be formed, and then performing the electroless copper plating on the catalyst of the board to form a circuit thereon, wherein an improvement comprises treating the roughened adhesive layer surface with an alkaline solution before depositing the catalyst thereon and treating the masked insulating board with an aqueous solution containing a surfactant before performing the electroless copper plating. The above process assures a higher copper utilization and a large adhesive strength of the copper plating to the board.

摘要： An image forming apparatus includes a transport belt, a carriage, a reflection sensor, and a control unit. The transport belt transports a recording sheet in a sub-scanning direction. The carriage, mounting a recording head, reciprocally moves in a main scanning direction to record an image on the recording sheet. The reflection sensor, mounted on the carriage, receives light reflected from the transport belt to detect a leading edge of the recording sheet, and outputs a detection signal corresponding to the received light. The control unit controls a contamination check process. The control unit instructs the carriage to move to a given position over the transport belt and to drive the transport belt for one rotation while maintaining the carriage at the given position. The control unit determines whether contamination exists on the transport belt based on the detection signal output from the reflection sensor.
