Abstract
Description
technical field
[0001] The invention belongs to the field of PCB production, in particular to a printing device for a PCB board, in particular to a resin ink vacuum plug hole printing device and a printing method thereof. Background technique
[0002] There are many holes on the surface of the PCB circuit board, and the holes on the surface need to be filled with resin to make the surface smooth. Now a vacuum plugging machine is often used to plug the holes in the technology. In order to make the filling uniform, the printing machine prints in a vacuum state, and the pressure difference generated by reducing the vacuum degree fills the resin to the depth of the hole. For example, install a printing machine in a container with a closed structure, open the door of the container, move the workbench with the printed circuit board on it into the container, and then vacuum the inside of the container with a vacuum pump while the door is closed. Printing is carried out in the case...
Examples
Embodiment
[0029] Such as figure 1 As shown, a resin ink vacuum plug hole printing device is disclosed in this embodiment, which includes a printing main chamber 5, and the above-mentioned printing main chamber 5 is the main working environment for the device to print a circuit board 6, so the above-mentioned printing main chamber 5 It is a vacuum printing environment during printing. After printing is completed in the above-mentioned main printing chamber 5, take out the printed circuit board or replace the circuit board to be printed. In order not to destroy the vacuum degree in the above-mentioned printing main chamber One side of 5 is provided with a transfer bin, and the above-mentioned printing main bin 5 and the transfer bin are connected, so printed circuit boards can be transferred between the above-mentioned printing main bin 5 and the transfer bin.
[0030] The above-mentioned transfer warehouse includes a warehouse body 1 and a warehouse cover plate 4 for sealing the warehous...
