Thermoformed semiconductor packaging
MC-77034
34-Cavity SOJ Tray
A 34-cavity tray with stepped rectangular pockets, based on a 32-lead SOJ application. Available in black conductive and clear antistatic material.
Does this tray look close to what you need? Send us your device information. Malaster can help review the fit, material choice and requirements for your application.
Discuss This Tray for Your Application
Mention MC-77034 when you contact us.

A starting point for your device
The MC-77034 arranges rectangular cavities around a central clear area within a 7.125″ square footprint. Each pocket has multiple levels, with separate outer and inner dimensional references.
SOJ devices have leads that curve under the body, so the lead profile and the way the body is supported need to be checked together. The outer cavity envelope should not be treated as a guaranteed device size.
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.

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 pocket geometry and central clear area. A side profile of the device helps us review the body seating level, J-lead clearance and access for removal.
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-77034 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-77034 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-77034 in your inquiry so we can refer to this tray design.
