The block diagram below shows a typical process flow for this Solvent Processor:
Micrographs of Solvent Resist Stripping on TFH Parts:
The two micrographs below illustrate the effectivity of a solvent process in stripping resist off the active parts of the head without removing the bonding adhesive from the tool/head. This is an example of selectivity in solvent reactions. The cleaning also removed all particles from both the air bearing surface and the head sides.
Note the resist marks on the center of the ABS of the head and on the edges. In addition some particles are evident (from their shape they are resist splatters). Note the cleanliness of the head after solvent processing.
