Section III. Maintenance
Thermode Maintenance
When a heat profile has been suitable for a particular application over many bonds, but poor quality
bonds are now resulting, thermode surface deterioration could be the problem. If you need to increase
heat period temperature and time to maintain the same bond quality, the thermode surface is probably
coated with heavy flux, adhesive or polyimide ribbon flex cable residue.
Clean the thermode surface either chemically with your vendor-recommended solvents, or mechanically
using number 600 grit (or finer) silicon carbide paper.
Replace thermodes that have become warped or cracked.
Warped thermodes will not adequately transfer heat to the parts.
Cracked thermodes will not heat, or they may overheat in the cracked area.
