About the system
Baichuan MES is the manufacturing execution system built by Shenzhen Baichuan Technology Co., Ltd., covering SMT, DIP, test, assembly and packaging — material loading error-proofing, process traceability, quality closure and shop-floor dashboards in one data set. Serving electronics factories since 2015 and live at 30+ manufacturers, its 15 modules combine freely by process stage — smallest start is wrong-material error-proofing and traceability on a single SMT line, no need for the full flow at once. Built for high-mix, low-volume plants in handsets, tablets, automotive electronics, FPC, WiFi modules, medical and energy storage; integrates with ERP, testers, aging racks and scales; supports on-premise deployment.
| Interception level | Interception method | Use cases |
|---|---|---|
| Level 1 | PDA scanning cross-checked against BOM and feeder placement table; mismatches trigger an alert and lock the PDA | Factories with limited budgets that need to stop wrong materials first |
| Level 2 | Level 1 + audible/visual alerts on the monitoring PC, linked reminders across the line | Shops running multiple lines that need on-site linked alerts |
| Level 3 | Level 2 + line-stop controller locks the placement machine; released automatically once resolved | High-value lines with zero tolerance for wrong materials |
In short: first plug the wrong-material and traceability gaps — wrong parts, skipped steps, broken traceability — then extend to production planning and equipment networking as needed. The four process stages can go live one by one, each accepted separately.

Process coverage
The four stages share 15 modules: pre-production covers material prep plus stencil and solder-paste records; front-end production covers placement station error-proofing and reflow profiles; back-end covers station-pass records, test parameters and part binding; packing & shipping covers weighing, cartoning and carton-SN binding. Every step leaves a data trail — no manual ledgers to backfill. Go live stage by stage: error-proofing and traceability first, the rest of the modules after.

Scale & Credentials
6 model factories open for visits (South, East and Southwest China), 18 service points across the Pearl River Delta, Yangtze River Delta, Chengdu-Chongqing and Southeast Asia — on-site issues answered from regional hubs. 12 qualifications and certificates — high-tech enterprise, dual software certification, ISO 9001, CMMI 3 and more — ready for tenders, supplier audits and customer factory inspections.
Modules
You don't need all 15 at once. The common path: start with SMT wrong-material error-proofing and traceability — one stage running in 4–8 weeks — then connect planning, quality closure and equipment networking once it's stable. Modules share one part-number, batch and SN scheme, so adding modules never means switching systems or migrating data.

Shop Floor
Output, attainment, equipment status, defect distribution, temperature and humidity are all collected live from the line — no double entry. Placement rejects, reflow profiles and test parameters land in the database automatically; defects over threshold and downtime are pushed to owners instantly. For shops that need mid-shift visibility instead of end-of-shift catch-up.
See dashboard featuresPlacement rejects, reflow profiles and test parameters are stored automatically — no manual logs.
Defects over threshold and equipment downtime are pushed to the owner in real time — no waiting for the end-of-shift review.
Look up material batches and stations by product, or trace where a material flowed by material.
Hardware
Hardware and MES share one data set: smart racks light up picks per the feeder placement table, support empty-reel material calls and overdue-reel alerts; environmental monitoring covers the solder-paste room and shop-floor temperature/humidity; scales prevent under- and over-packing; the MES data box connects older equipment without networking. Data lands in one place — swapping devices doesn't disturb the system.

Case Studies
From automotive electronics to smart terminals, scope and line shapes differ: Shenzhen Yidian runs three stages to reel-level traceability, Yingtang Precision went live across four stages with carton-SN binding, and Shanghai Sunmi covers assembly & packaging traceability. Each case spells out the background, the problem, what was done, and what was checked item by item at acceptance.

Covering SMT, DIP and assembly: incoming lots are checked against the reel loaded on the line, and traceability reaches reel level. When an audit asks for the material, station and test records of one SN, a single export replaces digging through three systems.

All four stages are live: SMT, DIP, assembly and packaging. Key components are bound by scan, and at packaging the carton number is bound to the SNs and verified by weight. Outbound lookup works by carton, and missing, extra or mixed items are stopped on the packing line.

Component binding and test-data collection went live together at the assembly stage, so a missing key-component binding is caught at the station.

Knowledge Base
Problems met on the line and how they were solved: the 7 links of solder-paste management, managing stencil life, why wrong materials slip through, and how unit traceability reaches reel level. Conclusion first, evidence after — for peers.
One board uses several reels and one reel feeds several boards — a many-to-many relation. Reel-level traceability can only be reconstructed from loading timestamps and the routing time window; there is no other way.
Steps get skipped in DIP not because operators forget, but because nothing enforces the order. Routing checks must hold three things: station sequence, no-skip rules and the rework return path.
A material error-proofing system checks feeder, part number and substitution relationships before placement, and blocks on mismatch. Blocking falls into three levels: scan prompt, scan-and-lock, and scan-and-lock plus splice verification.
FAQ
Questions are kept in customers' own words; answers follow the current version. Pricing and timelines follow the module list and implementation plan.
Priced by number of modules and process stages; a single stage (e.g. SMT error-proofing and traceability) can be deployed on its own. The common path starts with one stage from around RMB 100k, with full scope added module by module. The binding figure is the itemised quote in the module list and implementation plan.
A single stage (e.g. SMT error-proofing and traceability) typically goes live in 4–8 weeks. Full scope is implemented stage by stage, roughly 1–2 months each, depending on the number of lines, barcode rules and the scope of equipment integration.
Yes. The 15 modules combine freely by process stage. Customers have started from a single SMT line with error-proofing and traceability, then replicated it to other lines. There is no minimum line count.
No plant-wide shutdown is needed. Switch line by line: prepare barcode rules, BOM and feeder placement tables first, then bring lines on one at a time. A single line is usually switched during a changeover or planned stop.
Work orders can be imported from ERP (interface or staging table) with production status written back; we have integrated with several ERP systems. Work orders can also be created directly in MES — integration is optional.
On-premise deployment is supported: data stays on the customer's own server, and delivery includes the database schema documentation. For custom development, source code and schema notes are delivered per contract, with remote maintenance optional.
Reels are labelled with barcodes. At loading, the scan is checked against the BOM and the feeder placement table; a mismatch raises an alarm and blocks at the configured level: level 1 prompts and locks the PDA, level 2 adds audible and visual alerts on the monitoring PC, level 3 adds a line-stop controller that locks the placement machine. Every loading action is logged for traceability.
No. Changeover verification is done by scanning instead of checking each reel by hand, and every check is logged automatically. The feeder placement table and kitting list are generated before the changeover; at loading you only confirm by scan.
