We would like to introduce some of the main questions regarding circuit board design, manufacturing, component purchasing, component assembly, and inspection jigs. "Is it possible to request circuit board design from a hand-drawn circuit diagram?" and "Preparing component documentation is quite difficult." are some of the questions we have answered. For more details, please refer to the related links. 【Frequently Asked Questions (Partial)】 < Circuit Board Design > ■ Is it possible to request circuit board design from a hand-drawn circuit diagram? ■ How detailed does the circuit board design specification need to be? < Circuit Board Manufacturing > ■ I need the circuit board quickly; what is the possible timeline? ■ I would like to manufacture only 1 to 2 prototype circuit boards. * For more details, please refer to the PDF document or feel free to contact us.

• Contract manufacturing

We would like to introduce our business, "Electronic Equipment and Circuit Board Renovation." Many of the causes of failure in control devices and electronic equipment are due to issues with the internal circuit boards. We solve problems such as "It's been a long time since I bought it, so the manufacturer's warranty has expired," and "It's very expensive to buy a new one, and I'm really troubled." We repair items that can be fixed and recreate circuit boards with the same functions for those that cannot be repaired. Our company, with its technology and track record, is capable of providing these services. [Features] ■ Repair items that can be fixed - Repairs are only made to the necessary parts, so it can be done at a lower cost. ■ Recreate circuit boards with the same functions for items that cannot be fixed - Production is only for the necessary parts, so it can be done at a lower cost. *For more details, please refer to the PDF document or feel free to contact us.
