Secondary Operations

slicing of ferrite & dielectric substrates
automatic electrical sorting of ferrite toroids
Grinding (sintered:hard and green:soft): flat-th / od / id / form / drilling / milling
Slicing: (from 0.005 thick and 6 in. diameter)
Lapping: finish 0.2 – 0.4 µm
Polishing: finish 0.1 –0.2 µm (std.)
Optically Polished: finish 0.075 – 0.1 µm (less than 50 angstroms)
Hot Isostatic Pressing (HIP): (up to 1500 C and up to 30,000 psi)
- utilized for ferrite in magnetic heads in contact with tape, which require a dense
- material, virtually without pores and resistant to abrasion. also, due to near
- theoretical densities achieved, magnetic properties of most materials are
- significantly improved
Magnetizing: (axial, radial and multi-pole up to 10,000 oersteds)
Automatic & Manual Electrical Sorting/Grading: up to 10,000 parts/hour
Annealing: magnetic and thermal
Tumbling: edge rounding (prevents sharp edges from cutting wire insulation)
Marking: color coding/ identification
Coating: silicone/parylene (outsource) /epoxy (outsource)
Metallization: silver (outsource)
Winding, Leads, Tape & Reel: outsource
