300 Degree Polyimide Labels for Semiconductor and Printed Circuit Board Manufacturing Processes
- Polyimide film rated for short-duration exposure up to 300 °C
- Survives semiconductor backend packaging processes and high-temperature cure ovens
- High-temperature silicone adhesive stable at continuous 260 °C and short-peak 300 °C
- No thermal decomposition, discolouration, or dimensional change at rated temperatures
Description to 300 Degree Polyimide Labels for Semiconductor and Printed Circuit Board Manufacturing Processes
300 Degree Polyimide Labels for Semiconductor and Printed Circuit Board Manufacturing Processes are engineered for identification applications where process temperatures exceed the standard 260 °C reflow ceiling and approach the limits of what pressure-sensitive label materials can withstand.
- Standard polyimide labels rated to 260 °C may discolour, lose adhesion, or exhibit surface cracking under these extended high-temperature exposures; the 300 °C variant addresses this by using a higher-specification polyimide film formulation with an enhanced high-temperature silicone adhesive system that maintains its properties at elevated process temperatures.
- VIZLENT manufactures these labels for both carrier identification — marking JEDEC trays, waffle packs, gel packs, and component reels as they move through semiconductor assembly processes — and for direct substrate labelling where the label must survive the full thermal history of the PCB or ceramic substrate during manufacturing.

Frequently Asked Questions
Yes. VIZLENT produces 300 Degree Polyimide Labels for Semiconductor and PCB Manufacturing Processes in custom dimensions and die-cut shapes to fit specific carrier formats including JEDEC trays, waffle packs, gel packs, reels, and magazine tubes. We can incorporate variable data including lot codes, date codes, part numbers, and barcodes. Please provide your carrier drawing and labelling zone dimensions so we can ensure the label does not interfere with component pockets or handling features.
VIZLENT’s standard heat-resistant polyimide PCB labels are rated for continuous service at 260 °C and short-peak exposure at 260 °C under typical SMT reflow profiles. The 300 Degree variant uses a higher-specification polyimide film and an enhanced silicone adhesive formulated to maintain its properties at process temperatures above 260 °C — such as those encountered in semiconductor die attach cure ovens, epoxy underfill cures, and moulding compound post-cure steps. If your process peaks above 260 °C for any label position, specify the 300 °C rating and provide your time-temperature profile for VIZLENT to confirm suitability.
The standard MOQ for 300 Degree Polyimide Labels is 5,000 labels per SKU. Production lead time is 12–20 working days from specification confirmation, artwork approval, and deposit receipt — slightly longer than standard polyimide labels due to the higher-specification raw material procurement. VIZLENT recommends customers share their process time-temperature profile during the enquiry stage so the correct specification can be confirmed before production begins, avoiding costly specification changes after tooling.
VIZLENT recommends a process qualification step using sample labels before any production order for this product. We dispatch samples in standard sizes within 3–5 working days of request. Customers should subject the sample labels to their actual process time-temperature profile — including hold times at peak temperature — and then assess adhesion retention, label dimensional stability, print legibility, and any evidence of adhesive bleed or substrate contamination. We can also review your process profile and advise on expected label performance before you conduct the trial.
VIZLENT’s 300 Degree Polyimide Labels use a silicone adhesive and polyimide face material that produce minimal particulate generation under normal handling conditions, making them suitable for use on carriers and substrates in controlled manufacturing environments. For cleanroom Class 100 (ISO 5) or cleaner environments, we recommend customers perform particle generation testing on their specific label application and substrate combination. We can provide material composition information to support the customer’s cleanroom qualification review process upon request.
