　　Hall probe is Gauss meter main components, Beijing bolandun magnetoelectric Technology Co., Ltd. is the production of Gauss meter equipped with are BLDHALL high precision special metal Hall probe. Because of the cumbersome process, fine, rigorous, must be completed in the clean workshop production, but also because of the special technical and technological process, the workshop is prohibited to visit the.

A lot of time customers are curious about how such a sophisticated probe is made out of it? But every time we have to apologize for the refusal to visit the requirements of. To explain the mysterious place of magic BLDHALL series of Hall probe, we decided to slightly with your quest together.

BLDHALL series Hall probes are the material is not ordinary silicon, process is not an ordinary technology of growth, it is better linearity and sensitivity higher GaAs material, using the more advanced high concentration of ion implantation technique.

GaAs wafer

The wafer after the package to reduce measurement, laser scribing process, dot thin, polishing, and became an independent we die.

We become independent individuals.

Ultra-thin, ultra small, very high precision is the secret of these small single crystals do BLDHALL series of Hall probe can be, of a thickness of less than 0.2 mm, length less than 0.4mm, it is worthy of the name of the small body big wisdom, sensitivity, linearity, temperature characteristic and the stability are than ordinary Huo Er film to several levels.

The little guy, even after stretching with film, then the ball welding has higher technology.

Have you seen our armed forces? They are experienced senior personnel, after three months of theoretical training, six months of practical operation and training to be officially on duty.

Hall probe has superior performance and delicate body, so the requirement of the production environment particularly strict, temperature and humidity must be constant, and free of dust.

In dust-free workshop through two doors, for professional work clothes, work shoes, but also to electrostatic, the feeling will be into a mysterious world.

The little guy, even after stretching with film, then the ball welding has higher technology.

Workbench

After the ball has a series of complex process, high temperature aging, testing, packaging, re aging, re testing, re packaging, re testing, calibration, sorting...... Here is not to dwell on it.

You trust the bolandun magnetoelectric, thanks to the affirmation of BLDHALL series products, we will be dedicated to provide you with better products, better quality of service.

The little guy, even after stretching with film, then the ball welding has higher technology.
