Service the install base — across every fab, every recipe, every program.
Semi equipment OEMs ship multi-million-dollar platforms that run multiple customers' recipes, in multiple regions, against multiple qualification regimes — for a decade. Your internal QMS sits under ISO 9001 and SEMI S2 / S8 safety; DoD-adjacent platforms add CMMC 2.0. Your customers' fabs run qualification audits against PCN discipline, FSE certification, tool-matching, recipe portability, and SEMI E10 / E58 / E116 state. Wēlr is the install-base record that travels with the platform — and the evidence that holds up to every customer's qual.
Four pains across the post-sale service motion.
- 01
Customer support packages are a 2–4 hour Notepad job before diagnosis starts.
Field engineers spend hours extracting signal from telemetry archives — manually, in text editors — before they can begin diagnosing the actual failure. The parsing job is the bottleneck on every dispatch.
- 02
Field-engineer knowledge ages out faster than the install base.
Tribal knowledge walks out with senior FSEs. The next call that touches that chamber starts from scratch — the playbook your best engineer ran at one fab doesn't reach the next site automatically.
- 03
Each customer's qualification audit is rebuilt for the visit.
Per-tool, per-recipe, per-customer qualification evidence — chamber matching, drift posture, qualified-state log — is reconstructed each time a customer's QA team asks. Tier 1 customers ask often.
- 04
Customer-portal expectations are rising; building one is a multi-year project.
Major customers expect a structured portal with tool status, recipe execution evidence, parts ordering, and warranty status. Your customers' tool-acquisition team asks why your portal doesn't show what Tier 1 platforms already show — and your CTO has the multi-year build estimate.
Four primitives. One install-base record.
Structured support-package ingestion
Drop a support package into Wēlr — the telemetry engine discovers the schema, maps the metrics, and surfaces relevant signals in minutes. SECS / GEM, vendor FDC archives, and proprietary formats collapse to one normalized view. The 4-hour parsing job becomes the 4-minute review.
Cross-customer install-base intelligence
Every work order, qualification check, and drift event across the install base becomes searchable institutional knowledge. The chamber wet-clean SOP your best FSE ran at one fab is the playbook the next site inherits — with the caveats they captured.
Customer-facing qualification portal
Tool-matching evidence, recipe portability records, qualified-state per chamber, and drift posture surface to your customer's QA team through a scoped portal — by configuration, not project. Each customer sees only their fleet.
Warranty, parts demand, and component-survival forecasting
Weibull-fitted component-survival curves across the install base drive spares forecasting. Warranty consumption correlates to field events as they happen. The OEM finds out before the customer escalates.
Why not build it, or extend a service-cloud platform?
Most semi equipment OEMs face the same three options. Build in-house (multi-year project; specialized telemetry-ingest architecture; an FSE org that has to ship while engineering builds). Extend a generic service-cloud product (no telemetry parser; no qualification model; no cross-customer intelligence). Or Wēlr.
| Capability | Wēlr | Build in-house 24+ mo · 10 engineers · ~$5M | Generic service cloud ServiceMax · Salesforce FS · Maximo |
|---|---|---|---|
| Multi-customer install-base intelligence | First-class data model | Custom schema work | Not modeled |
| PCN status + FSE certification per customer fleet | First-class record | Custom build | Spreadsheet-tracked |
| Customer-facing qualification portal | Configuration, not a build | 18+ months to build | Not available |
| Support-package parser (SECS / GEM, FDC) | Minutes per package | Custom ingest pipeline | Manual extraction |
| Cross-fab chamber-match telemetry alerting | Immutable alert + dispatch link | FDC-side only, no FSE link | Not available |
| Time to first FSE dispatch on Wēlr | Weeks | 2+ years | Weeks, but limited |
Cross-customer chamber-match telemetry — the playbook the next FSE inherits.
A 24-hour RF-reflected-power anomaly at one customer's chamber goes from OEM-embedded-sensor alarm to fleet-wide situational awareness. Sites running the same recipe family on the same platform get a pre-arrival brief on the next dispatch. The pattern your best FSE caught at one fab becomes the next site's first hypothesis — not their week-three discovery.
- Telemetry sourced from OEM-embedded sensors (RF reflected power, MFC trend, chamber-match) — not customer FDC streams, per Tier 1 contract precedent
- Recipe-family join: cross-fab brief auto-attached to next dispatches at every site running the same family on the same platform
- Per-customer scoping enforced — Site A's data never visible to Site B at the database row
- SEMI E10 / E116 productive-state model paired with PCN status, FSE certification, and tool-match qualification on one record
If any of these are true, we should talk.
- ✓Your customer support packages are a 2–4 hour parsing job in Notepad before diagnosis can start.
- ✓A senior FSE's tribal knowledge of a recipe pattern walked out the door in the last 12 months, and the next call started from scratch.
- ✓A major fab's qualification audit found a gap the team traced to evidence that couldn't be reconstructed inside the response window.
- ✓Your VP of Sales keeps asking for a customer-facing tool-qualification portal, and your CTO has scoped it at $4M+ / 10 engineers / 24 months.
- ✓Your EMEA, US, and APAC FSE teams produce evidence in different formats and you reconcile them by spreadsheet.
