Sigma wire-bond strength comparison

xyztec b.v. · Packaging processes and engineering validation

Purpose: Compare bond strength and fracture locations after cycling/aging alongside heel-crack or lift evidence.
Technical approach: Sigma controls tool position/load and records force curves; wire/ribbon pull can continue to fracture or stop at a defined non-destructive load.
Scope of use: Select sensor, hook/tool, head and fixture for the loop, pads and load; keep comparison geometry consistent.
Limitations and open questions: These evaluation considerations are compiled by BLNKK from public information. They are not supplier guarantees or a mandatory submission checklist.
Scope and limitations
Pull force depends on angle, tool contact and fracture location; it is not individual-interface stress. Static strength or one proof load does not establish fatigue life.
What to prepare
BLNKK suggests preparing wire/geometry, aging/cycling history, test method and controls; retain curves, fracture images and sample coordinates.
Confirm with the supplier
Confirm sensor/tool, hook placement, speed, fixture and test mode. Agree on calibration, repeatability, fracture grading, comparison criteria and data export.
Public evidence: Official system/pull pages describe curves, failure grading and test modes, not module fatigue-life determination.
