Semiconductor handling
Determine whether electrically modified POM or another polymer fits a precision handling tray. Define the ESD class, process temperature, flatness, pocket geometry, cleanliness, automation, and reuse conditions together.
For matrix trays and molded carriers used to transport, store, sort, test, or present packaged semiconductor devices.
Pickup faults, device movement, ESD failures, particles, or warpage can originate in tray geometry, molding, conditioning, automation, handling, or compound behavior. Diagnose the complete process first.
Measure complete-tray flatness, pocket matrix, datums, outline, stacking features, conditioning, gate and flow orientation, cooling, and handler calibration.
Compare dimensionally controlled or reinforced materials only when tray architecture and molding balance are already credible.
Compare the full package drawing with pocket supports, terminal clearances, draft, corner relief, openings, flash, ejector witness, and loading method.
Screen a dimensionally stable molding material only after the pocket architecture protects the actual semiconductor package.
Define the applicable standard, electrical classification, conditioning, measurement locations, protected area, grounding or contact arrangement, humidity, and reuse state.
Evaluate conductive or static-dissipative POM only as a molded-tray system with verified electrical continuity and stability.
Identify filler or surface transfer, flash, trimming debris, damaged pockets, wear, cleaning effects, thermal exposure, and external handling sources.
Compare cleaner formulations or another material path only after the particle source and qualification limit are defined.
Candidate materials
Compare the options below against the ESD class, temperature window, flatness, pocket geometry, cleanliness, automation, and reuse conditions.
The primary POM option for trays that directly handle ESD-sensitive devices when its validated thermal window suits the process.
Resistance, charge behavior, filler cleanliness, flow, shrinkage, flatness, pocket dimensions, wear, and reuse stability require molded-tray qualification.
A reinforced option when tray stiffness or long-span deformation limits an otherwise suitable lower-temperature POM system.
Flow orientation can create directional shrinkage and warpage and can change ESD behavior or the surface exposed to the semiconductor.
An option for mechanical dividers, alignment parts, or associated handling components that do not directly require ESD control.
Conventional unfilled POM is not a default ESD-tray material; direct ESDS handling requires a verified electrical specification.
A separate path when process temperature, duration, loading, or reuse exceeds the validated POM window.
Higher thermal capability does not automatically qualify a bakeable tray; ESD, flatness, pocket accuracy, cleanliness, processing, and thermal cycles still govern approval.
Minimum project input
A drawing and the current operating conditions are enough to begin. Remaining details can follow after the first response.
After contact
The first response should eliminate unsuitable materials and define electrical, dimensional, thermal, cleanliness, device-fit, and automation tests. Production approval still depends on the molded tray and actual handling process.
Screen the device, tray standard, ESD requirement, process temperature, flatness, pocket geometry, automation, cleanliness, and reuse conditions.
Compare electrically modified POM or higher-temperature alternatives and, where verified, available grade data against the governing process risk.
Set electrical, dimensional, thermal, cleanliness, stacking, device-fit, and automation checks for production-intent trays.
A material-window decision, candidate shortlist, available grade data or document path, and a proposed molded-tray qualification plan.
Project input
Send the package drawing and available tray-standard, ESD, temperature, pocket, automation, cleanliness, and failure data. Taiyi Polymer can determine whether PLATFORM POM or another polymer merits molding, identify available grade data, and propose a tray-qualification plan.
