Semi-conductor/Substrate Inspection Components

Our probes can be made highly precise and durable due to our own in-house design and manufacturing. It is one of the important components used for the inspections of IC chips and substrates that is making a significant contribution to developing the world.

Mitaka has a standard line-up of wire probes ready to meet the market's increasing requirements for different pitches.

 

Contact Probes

Contact Probes

 

Contact probes require extremely delicate handling, as its performance varies by the dimensional tolerance between each part, the thickness of coating and its tolerance and the compatibility between individual parts. Therefore, solid experience and sensitivity/creativity are called for.

Drawing upon such experience, we offer customized products that meet our customers' requirements.

Probe Sockets

Probe Sockets

 

We offer high precision sockets with high heat resistance, made from machinable materials such as PEEK or PES.

manufacture them along with the mechanism required for its installation onto the customer's testing device.  

 

Wire Probes

Wire Probes

 

Electrodeposition coating is used to ensure smooth finish on the surface so that jigs can be mounted easily. Coating thickness is measured by the unit of μ, and the tolerance between the uncoated and coated areas can be controlled within ±0.05mm.
We can achieve consistent pin pressure and electrical resistivity. We offer durable and high quality wire probes at low cost.

Color: Blue, Red, Green and Orange
Plating: Ni, Au (for acrylic electrodeposition)
Coating: Acrylic electrodeposition (at a normal temperature)
