Priority items to confirm · 4
01Traceable evidence availableUnconfirmed
Have pad metallurgy, pitch, probe force and overtravel been checked?
Record total probe force, contact mode, pad/bump locations and marks; nominal compatibility does not establish valid contact.
Update engineering conditions →02Traceable evidence availableUnconfirmed
Are external instruments, guarding and calibration baselines traceable?
Use golden, open/blank and repeated-contact controls; verify the installed low-current configuration.
Update engineering conditions →03Traceable evidence availableUnconfirmed
Have chuck and actual DUT temperatures stabilized and been recorded?
Record settling time, self-heating, thermal contact and drift; chuck setpoint alone is not DUT-temperature evidence.
Update engineering conditions →04Traceable evidence availableUnconfirmed
Have the actual wafer/frame support and temperature-dependent coordinates been checked for comparability?
For ordinary wafers, record chuck support, locations and force. For framed diced devices, also check tape, thickness, die coordinates and thermal displacement. Explicitly mark unused frame/tape configurations as not applicable rather than inventing records.

The product page documents Apollo applications and probe, pitch, low-force and current options. The brochure download could not be read.
Scope and limitations Published options are not one simultaneous specification. Valid contact does not establish defect-free dies or identify internal failure causes. What to prepare BLNKK recommends preparing pad/bump maps, metals/pitch, current, temperature and test programs. Include planarity, overtravel, contact resistance and probe-mark references. Confirm with the supplier Confirm probe/transformer configuration, force/current/temperature windows and tester/prober compatibility. Discuss cleaning, lifetime and acceptable marks before subsequent bonding.
- MPI Corporation · TS200-SE low-noise thermal wafer probing ↗
View source notes and limits
MPI’s product page and August 2026 TS200-SE datasheet distinguish shielding, probes and chuck configurations, with separate temperature and leakage specifications.
Scope and limitations The station is not a standalone parameter analyzer or complete thermal-resistance test method; chuck temperature is not established device junction temperature. Leakage, temperature and high-power ratings depend on configuration and test conditions; do not combine different chuck or TS200-IFE specifications. What to prepare BLNKK suggests preparing wafer/device size, pad layout, voltage/current and temperature ranges, instruments and wiring, plus contact/overtravel, settling time and unloaded, open or reference-sample baselines. Confirm with the supplier Confirm the chuck, probes/guarding, instrument compatibility and leakage/noise under the intended conditions. Agree thermal verification, contact repeatability and measurement methods; junction-temperature or thermal-resistance work needs its own confirmed method and instruments.

View source notes and limits
ACCRETECH separately lists frame applications and options, including diced 300 mm-square and up-to-330 mm-square PLP testing.
Scope and limitations Correction does not diagnose buried opens. Probe card, test head and programs must be integrated; PLP/high-temperature capabilities are not default configurations. What to prepare BLNKK suggests preparing frame and die maps, dimensions and thickness, contact and probe-card information, test-head details, temperature conditions and contact-failure records. Confirm with the supplier Confirm frame/PLP formats, transfer/temperature options, coordinate calibration, needle-mark inspection and tester/probe-card compatibility.

What to prepare
- Named applications include copper pillars, solder bumps, flip-chip/pre-bump pads and area-array/perimeter layouts. Requires compatible test and wafer-probing equipment. Provide pad/bump pitch and metallurgy, current/patterns and temperature range. Prepare total force, overtravel/planarity, contact resistance, probe marks and cleaning comparisons.
- It supports configurations for device characterization, wafer-level reliability and failure analysis. Thermal options extend from −60 °C to +300 °C depending on the selected chuck and accessories. Provide accessible pads, external-instrument range/guarding, contact force and overtravel. Prepare chuck temperature/stabilization, blank/open/reference samples and noise baselines.
- 300 mm framed wafers and frame-mounted CSP/WLP devices. Confirm options for PLP, wafer dual transfer and high-temperature testing. Provide diced wafer/frame/tape support, unit coordinates/drift and pad maps. Prepare probe force, external test head/program, temperature options and post-probe mechanical checks.
