Manual Soldering Process

Manual Soldering Process

●Hand soldering certification
 (This permit is given to those who have completed the theory and practical training and met certain standards.)

For retrofit parts, only those with hand soldering certification are allowed to work on the job, and we strive to maintain and stabilize quality.

Assembly Process

Assembly Process
Various printed circuit boards are assembled into the main body (by screws and wiring) to create the finished product.
High temperature aging room
Environmental testing can also be carried out using Nippon Medical and Chemical Machinery's product (Max 100℃).

Electrical Inspection Process

Electrical Inspection Process
We conduct electrical inspections of the printed circuit board and main body of the product, and then finish it off as a finished product.
