High Reliability Processing & Ruggedization Options
General Standards Corporation offers a range of ordering options to meet the demands of harsh environments and mission-critical applications.
Available Options:
High Reliability Processing
If your application involves environmental fluctuations, power cycling, or requires high reliability, high-reliability processing is recommended. At GSC, High Reliability is more than just extended temperature support — it's a full suite of enhancements:
Included in High Reliability Processing:
- Manufactured to AS9100 standard
- Aircraft-qualified assembly
- Gold immersion finish (instead of ENIG)
- Extended temperature components rated -40°C to +85°C (ambient at board)
- Raw boards and large components cleaned and baked prior to assembly
- Use of leaded solder (where leaded BGAs are available)
- Solder paste height verification
- Cleanliness testing on one board per lot
- 72-hour burn-in while operating
- X-ray images of all BGAs provided for customer approval
- BGA damming to prevent contamination (using DOW Corning 3145 RTV)
- Conformal coating (Techspray Turbo Coat Acrylic 2108 or Fine-L-Kote SR 2102P)
- Post-assembly cleaning and baking
- Multi-stage testing to ensure low failure rate
- Full process tracking and documentation
- Failed parts are documented and retained
Pricing:
- HiRel processing: 1.75× the list price of the commercial version
- First run: $7,300 NRE (includes LOT charge)
- Subsequent orders: $4,000 LOT charge (includes X-rays, testing, and report)
Model Suffix:
Add "-HR" to the part number or include it as a separate line item on your purchase order.
Ruggedization
Boards can be ruggedized for extreme mechanical environments.
Example Upgrade:
- Base part: PMC-SIO4BX-256K-C
- New ruggedized part: PMC-SIO4BX-256K-I-RUG
Ruggedization Details:
- Conformal coating (Techspray 2108 or 2102P)
- RTV (Dow Corning 3145) added to jumpers/BGA edges
- EMI gasket (Gore EDR-21-010-0125-SC) between bezel and connector
- Threadlock (Loctite 242) on PCB and jack screws
- DIPs soldered directly (sockets removed)
- Updated labeling with conformal coating touch-up
Pricing: $500 per board
Industrial Temperature Versions
Operating Temperature Ranges:
- Standard: 0°C to +70°C* (Storage: -40°C to +85°C)
- Industrial: -40°C to +80°C* (Storage: -55°C to +125°C)
*Measured as ambient air temperature at the board surface.
Pricing: Add 30% to the list price for industrial temperature versions
Notes: No environmental screening included in this price. Boards are tested at 25°C.
Call for availability of environmental testing/screening. If a part is found to fail over the industrial temp range, it will be replaced at no charge to the customer.
Model Suffix: Add "-I" to the part number (e.g., PMC66-SIO4BXR-256K-I)
Conduction Cooled Versions
Pricing: 2× the list price
Minimum order: 5 boards
Model Prefix: Add "CC" to the part number (e.g., CCPMC66-14HSAI4)
Testing of Boards
- The boards will be designed following the CCPMC specification (see vita.com for ANSI/VITA 20-2001, the specification for conduction-cooled PMC boards). Components will be selected to operate over the full temperature range of -40°C to +85°C. However, this pricing includes only our standard in-house testing to commercial standards. GSC will not conduct environmental testing. Environmental testing is expected to be performed by the customer with the host board. Should any component fail during such extended temperature testing, it will be replaced at no charge.
Channel Requirements Clarification
-
In the event we are unable to provide all channels in a conduction-cooled version, please let us know:
1. What functionality or number of channels would you be willing to forgo?
2. What are your minimum channel requirements?
I/O Configuration
-
Our existing conduction-cooled board utilizes rear I/O.
The new conduction-cooled version will feature faceplate (front panel) I/O, which is compatible with conduction-cooled host cards that include removable thermal interface ribs. For details, refer to Table 2-1 (Compatibility Matrix) in the CCPMC specification (ANSI/VITA 20-2001).
Delivery
-
The initial delivery of the conduction-cooled version is estimated at 16 weeks ARO.
Conformal Coating
Model Suffix: Add "-C" to the part number
(e.g., PMC66-16AO16-16-F100-DF-C2108 or -C2102P)
Pricing: $400 per board (all form factors)
Coating Specs:
- Material: TECHSPRAY Turbo-Coat Acrylic 2108 or Fine-L-Kote SR 2102P
- Standards: UL94 V-0, IPC-CC-830, MIL-I-46058C
- Types: Acrylic or Silicone
