FAQ

SMIC M705 is used as the standard solder paste and thread solder.
A composition of (Sn Ag3,Cu0.5) is used in the flow tank.
Other manufacturers include Tamura Corp., Nihon Almit, and Nihon Handa.
Loctite 3609, Somakote IR-100, etc. are used as bonds.

The average number of boards produced is from 26,000 to 60,000. The maximum number of boards produced is 24,000.

Size M (250 x 300 mm) is the most common size. The average number of parts is 250 to 400 per board.
The average number of parts per LL size board (400 x 520 mm) is 2,000 to 5,000.
The average number of parts per XL size board (620 x 700 mm) is 2,000 to 8,000.

For larger size boards, surface mounting is possible for sizes up to 700 x 620 mm. Flow mounting is available for sizes up to 500 x 600 mm.
Rework is possible for board sizes up to 520 x 610 mm and thicknesses from 0.8 mm to 8 mm.

We have experience up to 0.3 mm pitch for QFP and 0.5 mm pitch between balls for BGA and CSP. The number of BGA balls mounted is 2,000 balls with shape angle of 70 mm.

Yes. General-purpose chip resistors and chip capacitors are in stock.
Other parts include chip coils, electrolytic capacitors, check terminals, light-emitting diodes, transistors, and ICs.

Green color is used to identify process signs, floor divisions, and tools used in RoHS compliant lines for each production item. Blue color is used for eutectic lines.
RoHS products are identified and managed from the order stage through design, material ordering, acceptance, release, manufacturing, inspection, electrical testing, packaging, and shipping using a dedicated line.

Based on the initial QA system, we obtain non-inclusion certificates for all delivered parts and handle sub-materials in the same manner, and if necessary, we also perform in-house analysis and measurement using X-ray fluorescence equipment.
We regularly analyze the solder components in the flow tank and also analyze and measure the shipped products using a fluorescent X-ray system to prevent contamination and ensure product assurance.

Lead-free solder is more expensive than eutectic solder, and nitrogen is used in reflow, flow, and soldering iron, so costs are higher, but not all costs are added.
We are also making efforts to reduce costs by introducing nitrogen generators. For specific costs, please request a quote for the actual machine.

VisualStudio C#

There are six engineers (four are in-house).

We mainly use 2D CAD.
・CAE2D
・Drafting
・Autocad Mechanical

SolidWorks is used for 3D CAD.

Broadcasting tables (sheet metal and wood tables), shelves, production equipment, jigs, etc.

This can be done in consultation with the customer.

Please provide a simple circuit, IC socket drawing, board shape, edge terminal table, and number of boards to be produced.

Yes, we can. We can also procure IC sockets for board production. Please contact us for custom parts.

Standard packages (QFP, BGA, etc.) have various test heads.

Electrical inspection is performed by burn-in board tester (ICT).

Ando Electric AF-8631 and Fujita RA-6020 are available for evaluation tests.

Yes, we can. High durability solder for burn-in only is also available.

Yes, we can propose materials that meet your requirements from among various materials.

Performance tests are conducted for digital video, RF, analog audio, and power supplies.

Oscilloscope
Digital Multimeter
Power Meter
Network Analyzer
Video Analyzer
Spectrum Analyzer
Audio Analyzer
DIGITAL MULTI-FORMAT MONITOR
Multi Monitor
etc.

If other equipment is needed for the work, we can rent or purchase it.

The processes are divided into different areas. The tools are also separated.

We carry out annual calibration by an external agency and pre-start inspection.

We mostly provide this service for units that were manufactured by our company, but we can also handle other types of products if you provide us with circuit diagrams and other information.
We also have a dedicated PCB department which can perform component replacement (chip, radial, and axial).
Electrical and aging tests are performed after replacement.

Normally, it is possible. Please contact us to discuss costs.

We have a consistent set of general-purpose products. The number of tools is expanded as needed depending on the frequency of use.

Construction is a demanding task, but we are able to perform everything from indoor installation to customer delivery inspection.
However, this is possible if there are no restrictions on personnel qualification. If you need specific qualifications, please contact us.

Although older workers are also active in special processes, we are in the process of switching to younger workers with the challenge of passing on skills as needed.

We provide nationwide support.

We have a department that provides this service and will consider the request.

We recommend our employees to obtain a national certification as an electronics assembly technician, and many of our employees hold this certification.
If you need some necessary qualifications, we will consider acquiring them.

We have a large number of requests for inspections only and have a proven track record.

We have general sub-materials in stock. We try to keep them based on the frequency of use.
