PRODUCTS
Hprobe magnetic field generator technologies address the challenges of magnetic integrated circuits industrial testing. The technologies are developed with the aim of generating high intensity magnetic field with extremely fast amplitude and angular sweep rate. The magnetic field generators are integrated into test equipment products dedicated for wafer level testing of magnetic device operating at high throughput.
Hprobe’s 3D magnetic field generators are patented technologies, compatible with the requirements of electrical wafer level probing requirement in mass production. The uniquely designed generators operate with power supplies and air cooling, so no complex liquid cooling is required.
- Compatible with 100–300 mm automated wafer probers
- Test head with integrated field generator mounted directly on the probing station
- Supports leading prober brands:
- TEL
