A cleanroom class describes particles in the air; the cleanliness of a tray's surface is accepted separately, against an agreed sampling method and limit.
05ESD & materials
Choose the material
for the protection needed.
Base materials
- A-PETClear, rigid
- PS (N)Easy to form, economical
- PP (N)Tough, fold-resistant
ESD protection
- StandardParts without ESD requirements
- AntistaticElectronics that must not build up charge
- ConductiveSensitive parts that need charge drained fast
ESD performance is confirmed against an agreed surface-resistance range and test conditions; trays that are washed are verified again after washing.

Do antistatic trays still need washing?+
It depends on how clean the part must be. Antistatic performance stops charge building up; it does not make a surface clean. Forming, cutting and handling can still leave particles and chips on a tray. Trays with cleanliness requirements are washed with DI water, dried clean, then inspected and packed in our class-100 room, and their ESD performance is checked again after washing.
How is cleanroom class different from tray cleanliness?+
A cleanroom class (such as class 10,000 or class 100) describes particle concentration in the air of a room. Tray cleanliness is what remains on the tray's surface, and is accepted separately against an agreed sampling method and limit. We control both: the room is monitored with a laser particle counter, and washed trays get a 20× magnified foreign-matter check.
