Welcome to Shoritsu Electric Industry website!  Printed Circuit Boards Implementation and Assembling Professionals

【Procurement / Production control】
We do accepting order, placing order, production control, stock control, and so on in order to control the production of parts and PC boards in this section.
Our original sales control system which is based on our knowledge and experience makes us possible to meet customer’s expectations.
【Manufacturing of PC board/ Product assembly】
It is possible to have lean manufacturing by dividing mounting process.
Even though we have more than 1,200 different kinds of production in a year, we can search production documents and plans immediately by using our original production control system.

【Checking / Shipment】
Checking and packaging before shipment are done in this section.
Mounted PC boards are to be visually checked as following the design which is defined by a customer.
This check is going to prevent defective products from being shipped.

【Technical support / Improvement of productive efficiency】
This section is functioned for improvement of productive efficiency, instruction and control of techniques, and maintenance of the equipments.
In order to have smooth manufacturing of PC board, we instruct how to use and maintain the equipments, and we also fix problems which are occurred in production process.

This is the front group of Mishima plant for manufacturing PC boards.

Customer service, accepting and placing orders, production control, and stock control are done in this group.
It is available for us to give some suggestions like replacing parts, cost-cutting, and so on.

Purchasing service

There are more than 200 electronic parts manufacturer which are connected with us.

If you have problems to purchase those parts, we can help you to find and introduce companies, or purchase them for you. Also, it is available to purchase from Asian manufacturer through Shoritsu (Shanghai) int’l co., ltd.

Accepting orders / Placing orders

As following customer’s request, the person in charge is to be accepting order and placing order to make up for the shortage parts.

Ordering process is done effectively by using our original sales control system.

Accepting parts

We ensure traceability of parts because of bar-code sticker which is attached to each part after checking name and number of each part.

Stock control

In order to control each customer’s stock, every parts are to be classified and stocked by each customer and recorded in the inventory book.

It is available to answer the inventory status promptly and clearly whenever you need.

Production control

The person in charge of placing order is to decide delivery date as understanding both expected delivery date by customer and capable delivery date by us.

Parts positioning and fabrication

Parts are to be became in kit before positioned to each manufacturing process.

By being read the bar-code sticker, we ensure first-in first-out system and traceability of parts.

Parts which need fabrication before they are mounted are in same system as above. Those parts are positioned to each manufacturing process after the fabrication.

Production group is the keystone of Mishima plant.
There are three teams, and each one is called the Automatic implementation team, the Robot implementation team, and the Assembly/ Checking team.
It is possible to have lean production by dividing production processes.

The Automatic implementation team

his group is for the process of automatic machine mounting and appearance check. We have three lines of automatic machine mounting.
There are nitrogen reflow ovens, and they make us possible to have high quality and equable mounting process. Automatic appearance check machines are applied for the appearance check.

The Robot implementation team

In robot implementation team, automatic soldering machines which are newly introduced are mainly applied for our production.
In the process of manual mounting and soldering mounting, parts which are hard to be mounted by machines are to be mounted by workers.
This process is done with automatic soldering machine in nitrogen gas atmosphere.

As cooperating with robot implementation team, automatic soldering machines which are newly introduced are applied for our production in order to enhance operation efficiency.
A bed of nails is also available for functional check. It depends on each customer’s request.
We use robots for soldering in the process in order to enhance operation efficiency and improve our quality.

Checking process

This is the process of checking of completed PC boards after mounting processes.
A bed of nails is also available for functional check.
We also write a program. It depends on each customer’s request.

Post-mounted process

Post-mounted process

Assembly process

Every PC board which has been checked in the checking process is to be assembled in this process.
