NEXTA DMA200 material viscoelastic characterization
Hitachi High-Tech · Material mechanical-property measurement
- Purpose
- Obtain temperature/frequency-dependent viscoelastic data for board/adhesive thermomechanical assessment.
- Technical approach
- NEXTA DMA200 applies dynamic loading in selected deformation modes to measure stiffness, damping and transitions.
- Scope of use
- Evaluate suitably prepared/clamped coupons matched to actual cure, orientation and moisture.
- 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 limitationsCoupon modulus does not establish assembled-BGA fatigue life or fracture cause. Confirm mode, cooling and observation configurations.
What to prepareBLNKK suggests preparing material/cure history, dimensions/orientation, moisture, temperatures/frequencies and amplitudes, checking clamps and linear strain.
Confirm with the supplierConfirm fixtures/configuration, measurement/calibration, glass-transition interpretation and relevance to actual cycling timescales.
