Electronics and electrical buyers increasingly specify cleanroom thermoformed trays instead of injection moulding or corrugated board. Here is where they are used and why they work.
Use it as a working checklist when you write your next enquiry.
This category covers a family of products rather than a single item. In practice a buyer defines cleanroom thermoformed trays by three things: the base resin, the format or dimension, and the performance or certification level it has to meet. Typical options in this category include low particle and low outgassing grades; double bagged packing; gauge 0.40 to 1.50 mm. Materials most often specified are Polyethylene Terephthalate Glycol, Polypropylene, Polystyrene, Polycarbonate, and the choice between them changes stiffness, temperature resistance, chemical behaviour and price.
In the electronics and electrical sector the decision is usually driven by ESD protection and dimensional accuracy, with cleanliness as a secondary requirement. Typical end uses include connector carriers, device inserts, accessory blisters.
Typical values for a general purpose grade are listed below; filled, stabilised and speciality compounds will differ.
| Material | Density | Tensile strength | Service temperature |
|---|---|---|---|
| Polycarbonate | 1.20 g/cm³ | 55-70 MPa | -40°C to 120°C |
| Polyethylene Terephthalate Glycol | 1.27 g/cm³ | 45-55 MPa | -40°C to 70°C |
| Polystyrene | 1.04-1.06 g/cm³ | 30-50 MPa | -20°C to 70°C |
Polyethylene Terephthalate is frequently the default selection here: High IV PET resin is the reason a 1.5 L bottle can be light yet hold carbonation pressure.
In the electronics and electrical sector, these are the applications where this product has proven itself.
Beyond the base resin, most suppliers offer UV stabilised, food contact, flame retardant, anti-static and recycled content versions of the same product. Ask which additive package is included, because it is often the difference between a part that lasts three years and one that lasts ten.
The route below is the one most factories use for this type of part.
Secondary operations such as printing, welding, machining and assembly are often cheaper to do in the same factory, and they reduce the risk of mismatch between components.
Use this checklist when comparing two or three supplier quotations.
Send this list to your supplier with the drawing and you will receive comparable quotations from every factory you contact.
Standard packing is export cartons on fumigation-free pallets, with custom labelling, barcode and retail packing available. We also handle consolidated containers and door to door delivery.
For standard sizes and colours the minimum is usually one pallet or one production run; for custom tooling the economic minimum depends on the tooling cost amortised over the expected volume. Send us your annual volume and we will calculate the break even point.
We can provide ISO 9001 quality system documentation, material certificates, RoHS and REACH statements, and where applicable food contact, flame retardancy or drinking water approvals. Tell us your target market and we will match the document set.
Yes. Standard samples are normally free of charge and shipped within three working days; custom samples are charged at cost and credited against the first production order.
Yes. {mat1} is one of our regular materials for this item, and we can supply virgin, modified and certified grades with full traceability. Material certificates and test reports are issued per batch.
Our team supplies cleanroom thermoformed trays to electronics and electrical customers worldwide, with samples, material certificates and full inspection reports available before mass production.
