PCB mounting

JOHNAN provides consistent services and assistance from product development and prototyping to mass production, including small-lot multi-product production.

JOHNAN offers consistent services and assistance from product development and prototyping to mass production. Providing various proposals to solve challenges relating to PCB mounting, we support high-quality manufacturing. We also flexibly respond to changes in mass production systems due to sudden fluctuations in production.

1. Features and strengths

(1) Providing a one-stop service


What can it be used for?

Providing consistent services from substrate design to production and inspection, we help reduce management man-hours and manufacturing costs. We have abundant experience in production support for fabless companies.

(2)Passion for manufacturing

Do you have no idea for manufacturing?

We help ensure high-quality manufacturing with careful consideration of productivity and quality. Our IPC-A-610 certified specialists and certified ESD coordinators respond to your requests.

(3) Consistent services and assistance from product development and prototyping to mass production

If you advise us from development to mass production process.

We help solve various challenges in PCB mounting from development and prototyping to mass production. With consideration of the improvement of productivity and quality, we offer proposals for substrate design, material procurement, manufacturing methods, and many other matters.

* IPC-A-610 is an inspection standard for the acceptability of electronic assemblies (quality standard for the production of electronic equipment). An ESD coordinator is a static electricity controller certified based on quality standards for manufacturing electronic equipment.
