The 10CL006YU256C8G is an Altera Cyclone 10 LP FPGA supplied in a 256-pin, 0.8 mm-pitch UBGA package and shipped in trays. According to the manufacturer’s specifications, the device is classified as Moisture Sensitivity Level 3 (MSL 3), with a floor life of 168 hours under conditions not exceeding 30°C and 60% relative humidity. For procurement and production teams, these parameters affect more than storage requirements. They may also influence whether incoming material can proceed into SMT production as scheduled.
1. What MSL 3 Means for Procurement and Production
MSL describes the sensitivity of plastic-encapsulated semiconductor devices to moisture exposure before reflow soldering. When a moisture-absorbed device is exposed to the high temperatures of reflow, vapor pressure can build within the package, increasing the risk of delamination or other package-related damage. For moisture-sensitive devices above MSL 1, Altera specifies handling and dry-pack procedures in accordance with applicable J-STD-033 requirements.
For the 10CL006YU256C8G, an MSL 3 rating does not indicate lower device reliability, nor does it represent a product expiration date. Instead, it defines how environmental exposure must be controlled after the dry package has been opened. Under the specified environmental conditions, the 168-hour floor life should be treated as cumulative exposure time. Material preparation, waiting for placement, split production runs, or repeated removal from controlled storage can all affect the remaining floor life and subsequent assembly planning.
The manufacturer’s product information also specifies a shelf life of 1,092 days. Shelf life should not be treated as equivalent to floor life, date code, or actual service life. For long-term inventory, storage duration alone is not sufficient to determine whether the material is ready for production. Packaging integrity, storage conditions, and available material records should also be considered. In other words, shelf life, floor life, date code, and device service life represent different aspects of material condition and should be evaluated separately.
2. Packaging and MSL Status to Check When Sourcing 10CL006YU256C8G
For an MSL 3 device, the date code alone does not indicate the current storage or moisture-exposure condition of the material. Even relatively recent devices may require further review before SMT assembly if the moisture-barrier packaging has already been opened or if storage records are incomplete. Conversely, an earlier date code should not by itself be used to determine whether a device is suitable for use.
When sourcing the 10CL006YU256C8G, procurement teams should check the following in addition to the part number, quantity, and date code:
- The manufacturer label, package type, and packaging format match the purchase requirements.
- The moisture-barrier packaging is intact, with clear MSL markings and related packaging information.
- The material is still in its original packaging or has been repackaged.
Lot, date-code, and other relevant material information is traceable.
For FPGAs intended for volume production, maintenance inventory, or long-term project support, confirming these details during the sourcing stage can be particularly valuable. Even when devices share the same electrical specifications, different inventory lots may differ in date code, packaging condition, and storage history. If a project has specific requirements for production timing, lot consistency, packaging condition, or traceability, those requirements are better communicated during quotation or order confirmation rather than after the material has arrived.
This information is relevant not only to incoming inspection but also to inventory and production planning. For material scheduled to move directly into production, packaging and moisture-management status may affect preparation and line scheduling. For FPGAs held as long-term inventory or used across multiple production runs, opening time and environmental exposure should continue to be managed during storage. Defining these requirements at the procurement stage can reduce additional verification caused by incomplete packaging, lot, or material-condition information after delivery.
3. Integrating MSL Management into Production Planning
The 10CL006YU256C8G uses a 256-pin UBGA package and is supplied in tray format. From a production-planning perspective, MSL management should therefore extend beyond warehouse storage. Material issue time, shop-floor temperature and humidity, waiting time before placement, and repeated opening of the same lot can all affect the remaining usable floor life.
This is particularly relevant for low-volume pilot builds, phased assembly, or projects in which material is purchased well before production. If the FPGA remains on the production floor for an extended period before placement, or if the same tray is opened repeatedly for multiple builds, recording cumulative exposure time helps maintain better control over production scheduling. It can also reduce delays caused by uncertainty about the material’s moisture-exposure status.
Reflow temperature should not be derived directly from the MSL 3 classification. MSL describes a device’s sensitivity to moisture exposure in combination with reflow thermal stress; it does not define a fixed soldering profile. The actual PCB assembly process should still take into account the package, solder-paste system, PCB thermal mass, and applicable manufacturing requirements.
For procurement teams, the MSL 3 rating of the 10CL006YU256C8G is more than a specification-sheet parameter. It can affect receiving, inventory control, and subsequent PCB production planning. Confirming the exact part number, package, packaging condition, date code, and traceability information during sourcing can help reduce additional verification after material arrival. For FPGA procurement of this type, WIN SOURCE can provide relevant material information according to customer requirements for lot, packaging, and delivery, helping procurement and downstream production teams maintain a clearer handoff between sourcing and assembly.
