Discuss This Tray for Your Application
Mention MC-77136 when you contact us.
A starting point for your device
The MC-77136 places six shaped cavities in a 10.250″ × 8.250″ footprint. Its stepped pocket geometry provides separate outer and inner profile references for reviewing the device body and surrounding clearance.
For a QFP device, the body, leads and underside must be reviewed together. Send the package drawing and lead details so we can check the appropriate seating surface and confirm the vertical fit.
If your device differs from the reference application, contact us anyway. We can discuss whether this tray, another existing design or a custom packaging solution is worth exploring.
Tray at a glance
| Tray reference | MC-77136 |
|---|---|
| Cavity layout | 6 cavities in a 3 × 2 arrangement |
| Reference application | 172-pin QFP reference design |
| Outer cavity profile reference | 2.505″ × 2.505″ Approximately 63.6 × 63.6 mm |
| Inner profile reference | 1.185″ × 1.185″ Approximately 30.1 × 30.1 mm |
| Reference depth to seating level | 0.080″ Approximately 2.0 mm |
| Overall footprint | 10.250″ × 8.250″ Approximately 260.3 × 209.6 mm |
| Reference overall height | 0.525″ Approximately 13.3 mm |
| Material options | Black conductive Clear antistatic |
Use these reference dimensions for an initial size comparison. Actual fit depends on the device profile, pin clearances and selected material. If your device is close to these dimensions, contact us to review the fit.
Look beyond the overall size
The line view shows the stepped profile, center features and surrounding access recesses. These should not be treated as a single, flat pocket or reduced to one maximum device-size claim.
Tell us how the tray will be used, whether for work-in-process handling, storage or a shipping application. We can then review the tray as part of the complete packaging requirement.
Choose a material for your application
MC-77136 is available in both black conductive and clear antistatic material. Tell us about your ESD requirements, handling environment and any need to see the device through the tray so we can discuss the appropriate option.
Black conductive
An option for applications requiring conductive tray material. Share your material or ESD specifications so we can review the requirements with you.
Clear antistatic
An option when clear material is useful for viewing the device. We can discuss the antistatic material requirements alongside fit and handling.
Could MC-77136 work for your device?
You do not need a complete specification to begin. Send what you have, and we can help identify the details needed to assess the tray and prepare a quotation.
- A device drawing, photograph, package outline or description
- Any known dimensions, pin clearances or handling concerns
- Your material preference or ESD requirements, if known
- Estimated quantities and timing
Please include MC-77136 in your inquiry so we can refer to this tray design.
