c- Before Processing Measurements

Measure the values of the resistors of each copper shape (if possible)using the multimeter or the multimeter and the power supply.

d- Paste Processing

1- Clean the paste residues using SW100

3-Let the paste dry, recommended drying conditions are in the table below:

4- Curing for 1 - 2h 30min. at 150 - 165 degrees Celsius.(Contact the company for IR-curing)

Application Procedure for Oven Curing

1.) put on mask and apron (use goggles if spraying paste using printer)

2.) establish a work area under hood in LDS

3.) mix paste (if reducing is needed) under the hood for sufficient ventilation

4.) use applicator to smear paste on pc-board

5.) cure past

6.) post processing/ cleanup
