MPW buyer question

MPW package/test scope before RFQ

Clarify wafer-only, bare-die, package, wafer-probe and packaged-test assumptions before asking MST for an MPW quote path.

RFQ non-confidential firstHuman confirmed route

Direct answer

What package/test details matter before an MPW RFQ?

MPW package/test scope should be described before quote review because wafer-only samples, bare die, QFN/BGA/WLCSP style assumptions, wafer probe, packaged functional test, load-board needs and logistics all change the execution path.

  • Early package/test assumptions help MST route the request to MPW, packaging/test, or prototype logistics support.
  • Buyers can share package preference and test expectation without sending schematics, layout, GDS or proprietary test code publicly.
  • Final package availability, test flow, sample quantity and schedule are quote-dependent.

What to prepare

  1. Preferred sample form: wafer, bare die or packaged units.
  2. Package assumption such as QFN, BGA, WLCSP, ceramic or open-cavity, if known.
  3. Need for wafer probe, packaged functional test, reliability, load board or socket support.
  4. Destination country and sample-handling constraints.

Public boundary

  1. A package/test preference is not a confirmed OSAT booking.
  2. Do not upload confidential test programs, schematics or design files through public intake.
  3. MST confirms package/test feasibility after partner and compliance review.

Share a short non-confidential brief first. MST screens node, process, PDK/NDA, package/test, schedule, country and end-use before any sensitive design-file path.
