Safety Conditions

Before open the paste please read SDS File:ED7100 OSHA MSDS.pdf for the paste. Be sure that the following are available:

Working with paste is highly recommended under a good ventilation area, the hood is a good environment for work.

Wear a well fitted NIOSH approved or industrial type canister mask.[1], [2]

disposable apron

1- Gloves,goggles.

2- suitable protection clothes.

disposable apron

3- sack of sand or absorber for cleaning the area.

ED7100 paste thickness effect on the electrical resistance of copper based material.

ER7 reducer, SW100.

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

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)

-- Printing the paste using 55 to 77T polyester mesh. For tight resistances tolerance use 200 mesh stainless steel screen to reduce the distortion. try to get a uniform surface.
