内面研削ホイール

Various types of non-woven abrasives, such as our SPIRAL
CUTTER, are used during each manufacturing process of PCB.

Abrasives for PCB

Due to our advanced technology, our abrasives achieve high quality and long life.

In accompanying of densification and miniaturization of substrates, our abrasives are applied for polishing fine patterned substrates and multilayer substrates as well as single-sided substrate and double-sided substrate.
 
Product Name Product Applications Features & Benefits  
SPIRAL CUTTER ・Removing permanent hole plugging ink.
・Polishing SUS-made press plate

This elastic grinding wheel is developed based on our know-how and advanced manufacturing technologies combined with coated and bonded abrasives.

SPIRAL CUTTER (Product introduction)

SKY WHEEL ・Deburring after drilling. (before copper plating)
・Grinding prior to dry-film lamination.
Uniform surface finish without polishing variation and wild scratches.
Improved durability contributes to a cost reduction.
ZERO WHEEL ・Deburring after drilling. (before copper plating)
・Grinding prior to dry-film lamination
・Surface finishing prior to solder resist.
By employing ultra fine fibers thinly coated with resin bond realizes minifying of buff dust size and improves uniformity of abrasive coating.
This contributes to minimize clogging of holes and improve surface roughness, so that uniform surface finish without polishing variation and wild scratches can be obtained.
BLADE WHEEL ・Removing permanent hole plugging ink.
・Polishing SUS-made press plate.
Due to high grinding ability, this wheel is suitable for removing hole plugging ink.
VC WHEEL ・Removing permanent hole plugging ink.
・Polishing SUS-made press plate.
VC WHEEL is a convolute wheel with grinding ability.
P-FLAP WHEEL ・Surface finishing prior to solder resist. This wheel has the moderately flexible structure,
which provides gentle cleaning action on the surface of PCB.
P-GANGED WHEEL ・Polishing SUS-made press plate Due to high grinding ability and moderate flexibility, this wheel provides gentle cleaning action on the surface of PCB.
