Accurate and simple code reading of direct parts marking

For the problem of additional time and effort and costs of code reader adjustment

The effort and cost of adjusting the code reader is one barrier

In recent years, "Direct Parts Marking (DPM)", which directly engraves a code on a part, has become mainstream at production sites where traceability is important. DPM is characterized by being able to print codes on small parts where it is difficult to attach labels, and is used in various industries such as electronic parts and medical equipment.

I think there are many semiconductor manufacturers who have already introduced DPM or are currently considering introducing it. It is a very useful DPM especially at production sites where there are many small parts, but one of the issues is that it is difficult to install a code reader when introducing it. Depending on the material on which the code is engraved, there are cases where it cannot be read normally due to reasons such as a small contrast ratio and reflection of light from the outside. In such a case, it is necessary to shift the line to a position that is not affected by ambient light, install a separate lighting for the cord reader, and fine-tune the angle of the cord reader, which is troublesome to install and adjust. It was costly. A designer who knows this situation may have been looking for a code reader that can be read easily and accurately.

High-performance and multifunctional code reader that meets various needs in the field

A recently common method at production sites where traceability is a major concern is to perform "Direct Parts Marking" (DPM) in which a code is directly marked on the parts themselves. DPM of parts that are too small for affixing a label consists of inscribing the part with the code, allowing it to be used for a wide variety of industries such as electronic parts and medical equipment. Many semiconductor manufacturers probably have already introduced DPM or are probably currently studying its introduction.

IDEC offers a code reader "WB2F fixed 2D code scanner" that has high reading performance and automatically adjusts the reading. The "WB2F fixed 2D code scanner" is equipped with a 1.2 megapixel CMOS image sensor and can read a wide range from a distance of up to 150 mm. The high pixel sensor and auto tuning function greatly reduce the man-hours for adjustment.

Also, since DPM prints a code for each part, there are multiple codes in the finished product after assembling the parts. Since the "WB2F type" can read multiple codes with different distances from the printed surface at the same time, you can freely read only one code depending on the line, or read multiple codes at once.

Since there is a function to save the image in case of reading error, even if there is a problem, the cause can be immediately identified and smooth countermeasures are possible.

A diverse lineup of control equipment that solves problems at production sites

IDEC has a wide range of control equipment such as code readers, PLCs, programmable indicators, pushbutton switches, indicator lights, and relays. If you have any problems solving problems at the production site, please feel free to contact IDEC.
