Safety Conditions

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

Ventilation

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

Poor Ventilation area

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


disposable apron
Paste Splashing

1- Gloves,goggles.

2- suitable protection clothes.

disposable apron


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

Technical procedure

Aim

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

a- Look at the safety conditions before using the paste.
b- Equipment And Tools
ER7 reducer, SW100.
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)
