Why JEDEC trays use MPPO Material (Modified PPO)
High Heat Resistance
MPPO has a high glass transition temperature (BAKE/12H MAX 150 °C).
Trays can withstand reflow soldering and baking processes without warping.
Low Moisture Absorption
Water uptake is extremely low (<0.1%).
Ensures dimensional stability in humid environments (important for IC packaging and storage).
Excellent Dimensional Stability and Low Coefficient of Thermal Expansion (CTE)
JEDEC trays need tight tolerances for cavity fit, stacking, and automated pick-and-place — MPPO provides that.
Good Mechanical Strength
Rigid but not brittle.
Withstands stacking pressure, robotic handling, and shipping vibration without cracking.
ESD Protection
Easily compounded with carbon fibers, carbon black, or antistatic agents.
Surface resistivity can be tuned from 10⁴–10¹¹ Ω/sq, which is the required range for safe IC handling.
Chemical Resistance
Resistant to fluxes, cleaning solvents, and chemicals used in semiconductor processing.
Extends the service life of trays.
Balanced Cost-Performance
Compared to exotic materials like PEEK, PES, or PI, MPPO offers a much lower cost while still meeting JEDEC’s thermal, ESD, and mechanical requirements.
Widely used for the packaging, storage, and transportation of IC packages, semiconductor chips, electronic modules, and optical devices.
