Exaddon developed a unique micro 3D Printing technology that enables it to produce probes that can access and test pads and bumps with pitches of less than 20 micron. The company says that this unique method halves the current limit of fine-pitch probing, enabling microLED developers testing options that haven't been available before.
Exaddon's μ3D printing technology delivers high quality printed metal with micrometer resolution. Exaddon’s initial microLED test array is 3D printed directly on prepatterned traces with a pitch of less than 20 μm; This demonstrator validates Exaddon’s process on microPCBs for mounting on current probe heads. With 128 probes, the array gives microLED testers a 64x increase in efficiency.
