Circuit Board Label & PCB Labels

VIZLENT’s standard guidance is to select the label specification based on two primary factors: the maximum temperature the label will experience during any process step, and the substrate surface the label will be applied to. If the label is applied before SMT reflow (peak ≤ 260 °C), specify polyimide face with silicone adhesive. If applied post-solder with a maximum service temperature below 150 °C, high-temperature PET with acrylic adhesive is sufficient. For ambient-temperature applications on assembled boards, standard PET labels provide an economical solution. Our sales and technical team can advise on the correct specification once you provide your process temperature profile and substrate type.

Yes. For boards that undergo SMT reflow during manufacture and then operate at elevated temperatures in the field — such as automotive ECUs, industrial motor drive boards, or outdoor power electronics — VIZLENT specifies polyimide face with silicone adhesive as both the process-stable and the field-service-stable solution. Polyimide is rated for continuous service at up to 260 °C, well above the field operating temperature of most electronic equipment, and the silicone adhesive maintains its bond strength over the full temperature range the board will experience in service.

The standard MOQ is 5,000 labels per SKU (size, face material, adhesive, and print content combination). For customers ordering multiple label sizes for a single PCB programme — for example, a large board identification label and a smaller sub-assembly traceability label — VIZLENT can discuss combined-volume pricing where the aggregate quantity across SKUs meets a threshold. Production lead time is 10–18 working days from artwork approval and deposit receipt for each SKU.

Ribbon selection depends on the face material and the thermal stress the label will encounter. For polyimide face labels destined for reflow soldering, VIZLENT strongly recommends a full-resin thermal-transfer ribbon, which produces print that is resistant to the thermal and chemical stresses of reflow and post-solder cleaning. Wax and wax-resin ribbons are not suitable for high-temperature service as the print may smear or transfer at elevated temperatures. For standard-temperature PET PCB labels in ambient-service applications, a wax-resin ribbon provides a good balance of print durability and cost.

Yes. VIZLENT offers a hybrid format where fixed content — company name, part number, revision code, logo, and fixed barcode symbology structure — is factory-printed in advance, leaving a defined blank zone on the label for in-house thermal-transfer overprinting of variable data such as serial numbers or date codes. This approach combines the quality and consistency of factory printing for fixed elements with the flexibility of in-house printing for variable content, and is particularly useful for customers who produce multiple product variants on a single PCB platform and need to differentiate labels at the point of use.
