Paste Printing Heads
If repairs are needed, it is often necessary to put new solder paste on the PCB pads. Normal screen or stencil printing will not be possible because the area around the repair place is restricted. To overcome this problem, a new printing head for local and precise positioned paste dispensing was developed which can be inserted into the reflow arm like a soldering head.
The procedure can be done quickly by moving the FINEPLACER® Alignment System’s table: Like placing components, the pictures of stencil holes and PCB pads are brought into alignment. After this, the reflow arm can be lowered, and the solder paste can be printed with a manual squeegee. |
