Printing Guide | 277-3 Conductive Paste

Recommended printing conditions and process for optimal conductivity with 277-3.

Printing Conditions

Humidity 50-80%
Temperature Room temperature
Squeegee Hardness 75 degree (oil-based)
Mesh Count 100-150 mesh
Curing Temperature 130-140°C
Curing Time 90 seconds

Printing Process

1

Add 1% PC-100 cross-linker to 277-3 paste and stir thoroughly. Use within 8 hours.

2

Print directly 1-3 times. For a smoother finish, apply 2-3 layers of underbase first.

3

Cure at 130-140°C for 90 seconds. Full electrical and mechanical properties develop after 24 hours of drying.
