Printing Workers:
3.5.1 Check if the air pressure is 4~5kgf/cm2, if not, please return to the specified value.
3.5.2 The solder paste must be thawed 4H in advance to restore it to 20~25 degrees.
3.5.3 Select the steel mesh according to the PCB P/N. Install the steel mesh on the printing table and confirm that the steel mesh hole and the PCB pad are completely right. Positive, adjust the alignment of the screen printing station.
3.5.4 Take an appropriate amount of solder paste on the stencil for printing; start printing.
3.5.5 After printing, take the printed PCB to check if there is any deviation, less tin, short circuit, etc.
3.5.6 When the production is completed, click the “Stop” touch screen to return to the main interface.
3.5.7 Turn off the power and air supply switch.
Operator:
3.6.1 Machine and surrounding 5S
3.6.2 Mounter operation, stock preparation and material replacement
3.6.3 The first PCB produced by the pilot production must be tracked from the first machine to the end of the last machine.
3.6.4 If there is a problem with the machine or some quality problems raised by the visual inspection personnel, solve it immediately. If it can't be solved within 10 minutes in a short time, please report it to the team leader or technician to help him solve it.
3.6.5 Do a good job in the production report, the daily production quantity and the cumulative quantity must be checked clearly and must not be mistaken.
3.6.6 Every 4H in the production process should be re-checked again according to the above display on the machine.
