Probe card and load board engineers own the physical interface hardware that connects a device under test to the tester channel electronics, whether at wafer probe or package-level final test. Their work spans electrical design review, mechanical fit, contact reliability, and signal integrity, and it has to hold up across thousands of touchdowns or insertions without drifting.
This is a hardware-first discipline. Engineers need to read schematics and mechanical drawings fluently, understand pin electronics and parametric requirements, and work with probe and socket vendors to resolve contact resistance, planarity and durability issues. When a probe card or load board fails in production, the engineer is expected to diagnose whether the fault lies in the hardware, the handler interface, or the device itself.
Because this hardware sits on the critical path for every new product introduction, lead times and qualification discipline matter as much as technical depth. Nirji Semicon treats this as a specialised workforce category, pairing candidates who already understand contact technology with client-specific onboarding on the exact probe or socket types used at a given site.
