Due to higily precise masking position,probe length when attached to jig would be uniform…result in uniform pin pressure and electric resistivity.
●
Smooth surface condition enables attachment to the jig much easier result in shorter working time on test process.Moreover,stabilizes inspection result as it minimizes conflict on each other probes,when pressure would be applied to the probes,
●
We can provide high quality,durable probe with higher cost performance of ownership.
■Comparison between conventional fluoroplymer coatings
Electrocoating by Tulip
Conventional Fluoropolymer Coating
Smooth surface condition and accurate masking position
Irreguler surface and inaccurate masking postion
Highly Precise Masking Position
Electro Coating Probe
Fluoropolymer Coating Probe
Highly accurate masking position enables constant probe height when installed to test fixture.
Masking position of conventional fluoropolymer coating technology is unstable.
Therefore height against substrate will be irregular.
Drops test reliability.

■1million Cycle Test Date
・Set New Electro Coating Probes to test fixture. Then apply dummy substrate to simulate similar movement to the actual usage.
Then verify durability of New Electro Coating Probes by inspecting surface condition
( existent/non-existent of breakage or deformation), resistance and insulation.
＊Pushed Stoke : 0.1mm Hit Surface : Brass n : 10pcs.
Result : No change on probe contact part and surface on Electro Coating part has been observed.

Insulation Resistance Measurement:500V(HIOKI’s digital MΩ high tester)
Specification on above : φ０．０９×３０ｍｍ
Measured by touching to both non-insulated part and insulated part.
All the insulated part has not conductivity.
