In SMT workshops, solder paste is a small but critical material that directly affects product quality and production efficiency. Many factory managers face similar headaches: dedicated staff are required even for small production lines; huge time is spent on tempering, mixing and manual recording; old and new paste are often mixed, leading to expiration and scrap; quality issues take days to trace through paper logs.

Managing s‍older paste efficiently does not need so much labor. Today we share a lightweight solution proven by over 1,000 enterprises — the Xutong Intelligent Solder Paste Cabinet. It enables precise full-lifecycle control with minimal manpower.

Traditional Solder Paste Management: High Labor Cost & Frequent Problems

Most factories still rely on traditional management:

Dedicated operators for storage, refrigeration, tempering, mixing and logging

Tedious manual timing, mixing and paper records

nconsistent tempering and mixing, low FIFO compliance, causing up to 22% solder paste waste

Difficult traceability due to lost or altered paper records

Risk of temperature excursions during unattended periods (nights or holidays)

These issues raise labor costs and lower production yield. Solder paste mismanagement accounts for a large share of soldering defects in SMT production.

Xutong Intelligent Solder Paste Cabinet: From Manual to System-Driven Control

The Xutong cabinet is more than an upgraded refrigerator. It is a systematic solution that redefines solder paste management. With integrated software and hardware, it automates the entire process: scanning → refrigeration → automatic tempering → mixing → dispensing → recovery → disposal.

Fully Automated Process, Greatly Reducing Labor

Automatic data entry via barcode scanning

Auto tempering in normal or scheduled mode, cutting preparation time by over 60%

Standardized automatic mixing with adjustable speed and time

Strict FIFO and leftover-first dispensing logic enforced by the system

Automatic recovery with usage limits (e.g., max 3 dispenses per bottle)

One large EMS factory reduced solder paste management staff from 2 to the equivalent of 0.5 FTE, saving over ¥100,000 annually.

Industrial-Grade Precision Temperature Control

Unlike ordinary fridges with ±5℃ fluctuation, Xutong uses imported Secop compressors and optimized air circulation to keep temperature variation within ±0.5℃ (tested at 25℃ ambient).

Dual temperature & humidity sensors for high reliability

Fast temperature recovery after frequent door openings

Excellent heat retention: temperature remains below 10℃ for 2 hours after power failure (at 25℃ room temperature)

Real-time alarm for abnormal conditions

A leading power battery manufacturer reduced solder paste-related defects by 35% and scrap rate from 22% to 7%.

Strict FIFO, Eliminating Waste

The cabinet uses unique barcodes, independent compartments and system-enforced dispensing to fully implement FIFO:

Each bottle has a dedicated slot to avoid mixing

System automatically recommends the earliest batch

Expiration alerts and automatic locking of overdue paste

FIFO compliance increased from below 40% to 100%, and expiration waste dropped by over 85%.

Full-Link Traceability for Audits

The system generates a digital profile for each solder paste bottle, automatically recording batch, temperature history, tempering time, mixing parameters, operators and work orders. It supports audit-ready logs, curves and reports.

Problem tracing time is reduced from days to within 30 minutes.
A top automotive electronics supplier passed multiple audits smoothly without manual paperwork.

Strong System Integration for Digital Management

The cabinet supports WebAPI, TCP/IP, RS485, MQTT and can be integrated with MES, ERP, WMS within 1–3 days:

Real-time data synchronization

Work order-driven dispensing to prevent misuse

Centralized remote monitoring via cloud platform

Solutions for Different Factories

Small factories (1–3 lines): SP-300 (300 bottles)

Medium factories (4–10 lines): HC-800 (800 bottles, MES-ready)

Large factories (10+ lines): networked multi-unit deployment

Conclusion

As digital transformation sweeps manufacturing, intelligent equipment replaces repetitive labor. The Xutong Intelligent Solder Paste Cabinet cuts labor costs, improves quality, reduces waste and enhances efficiency.

If you struggle with solder paste management, choose Xutong — let professional equipment handle professional work, and free your staff for higher-value tasks.
