CASE 3
Balancing quality and cost with conductive dust-free paper
Client's Problem
Interleaving paper with a film base was used to protect the products when shipping wafers and storing them iin-house. Since the film is durable, it was assumed that it would be reused but they were worried of the high cost because they weren't able to collect all of it. They were looking for a material that has the same performance as conventional film substrates and that can reduce cost even when used in one way. They consulted on whether there was a material that would meet the required quality, such as no dust generation, static electricity countermeasures, lower cost than film, and 1-way use.
Proposed Product

AS STACLEAN
The STACLEAN (dust-free paper) NB series, which is a conventional interleaving paper type, was evaluated, but the electrostatic level was 10 x 11 Ω, so we could not meet the customer's request.
Therefore, we devised a dust-free paper in which special conductive fibers are kneaded, and proposed this as a new base material to replace film.
Thing only Sakurai can do
We were able to develop a new product that imparts conductivity to STACLEAN (dust-free paper). I believe that Sakurai, who has the planning and development capabilities of a dedicated sales force and the brand of STACLEAN, was able to meet the needs of our customers.
