The Digital Backbone
BOM-Driven Automation
Our MES automatically ingests Bill of Materials (BOM) data to trigger intelligent material preparation, drastically reducing manual preparation time and ensuring accuracy.
One Component, One Code
Every material item receives a unique system-generated identifier upon receipt, enabling end-to-end scannable tracking and absolute traceability.
Real-time Verification & Error-Proofing
Operators use scanners to validate material serial numbers against the work order, eliminating assembly mistakes at the source and saving significant rework costs.
Audit-Ready Records
All production, storage, and handling records are permanently retained and can be exported on demand, providing detailed traceability reports for compliance.
Moisture Sensitive Device (MSD) Control
🔧 What Is MSD and Why It Matters
Moisture Sensitive Devices (MSDs) are electronic components that absorb moisture from the environment. If improperly stored, this moisture can expand during reflow soldering, leading to internal delamination, cracking, or popcorning. Correct MSL handling prevents these failures and protects product integrity.
📦 Level 2 Devices – Long-Term Vacuum Storage
Components rated MSL Level 2 must be stored in vacuum-sealed packaging with desiccants. This ensures a floor life of up to one year, eliminating moisture exposure. Baking is not needed if the packaging remains intact. Ideal for stable storage and predictable production schedules.
💧 Levels 2A to 5A – Strict 24-Hour Floor Life
For components with MSL Level 2A to 5A, dry cabinet storage is essential. Once removed, they must be assembled within 24 hours. If exposed longer, they require baking at 125°C for 24 hours to remove absorbed moisture. Accurate tracking of exposure time is mandatory.
⚠️ Level 6 Devices – No Room for Delay
Level 6 components are highly sensitive to humidity and must be assembled immediately upon unpacking. No floor life is granted. Mandatory baking is required before use, regardless of storage history. These parts demand tightly controlled production scheduling.
| MSL Level | Storage Method | Floor Life | Baking Requirements |
|---|---|---|---|
| Level 2 | Vacuum + desiccant packaging | 1 year | Not required |
| Level 2A–5A | Dry cabinet storage | 24 hours | 125°C / 24 hours |
| Level 6 | Immediate use required | No buffer time | Mandatory pre-baking |
Specialized Handling & Compliance
We master the complexity of sensitive electronics handling, ensuring every component meets the highest standards of quality and security.
Moisture Sensitive Device (MSD) Management
We enforce strict, documented protocols based on each component’s Moisture Sensitivity Level (MSL) in compliance with J-STD-033. This meticulous process translates to higher solderability, fewer assembly defects, and improved long-term reliability for your products.
Customer-Supplied Material Management
Your materials are stored in a dedicated, physically separate, and access-controlled zone. Each item is labeled with a unique identifier and mapped to your project’s BOM in our MES, giving you full visibility and control over your valuable assets.
Frequently Asked Questions
Proactively addressing common questions to build confidence.
Do you support projects where we provide some of the materials?
Absolutely. We have a dedicated management system with a segregated storage area to ensure your materials are handled securely and independently, eliminating any risk of mixing.
How do you guarantee the proper handling of moisture-sensitive devices(MSDs)?
We enforce strict MSL-based protocols, including controlled storage, mandatory baking when required, and full digital logging of every step. All handling records are traceable in our MES.
My project requires components to be baked for 48 hours. Can yousupport this?
Yes. Our facility is equipped with professional baking ovens capable of handling extended-duration baking cycles to meet the requirements of even the most sensitive components.
Can we get a report of which materials were used in our products?
Yes. We can provide complete material traceability reports exported directly from our MES system, suitable for your internal audits and quality assurance needs.
