What Performance Does Electronic Product Labeling Require? 4 Core Performance Requirements + 3 Selection Categories
💡 💡 At a Glance
Comprehensive Analysis of Performance Requirements, Material Selection, and Compliance Guidelines for Electronic Product Labels.
Last week, a customer who manufactures PCB boards asked me, "I need traceability labels for PCB boards. The labels will be exposed to solder splashes. What kind of label can withstand that?"
I said, "4 Essential Performance Requirements—antistatic, chemical-resistant, tear-resistant, and high-temperature-resistant."
He asked, "Which four?"
I said, "4 Core Performance Properties—this is what most clearly distinguishes electronic labels from ordinary labels. This article will not discuss "ordinary electronic labels"—it will cover 4 performance properties, 3 types of electronic products, a 5-step selection process, and 3-step testing."

FAQ
What properties should electronic product labels have?
Four Core Performances: (1) Anti-static (ESD) – prevents breakdown of electronic components, surface resistance 10^6–10^9 Ω; (2) Chemical resistance – resistant to alcohol / acetone / ink (no shedding after wiping with cleaners); (4) High-temperature resistance – withstands reflow soldering at 150 °C + wave soldering at 260 °C. Three categories of electronic products have different performance requirements: consumer electronics (medium) / industrial electronics (high) / PCBs (extremely high).
How to Choose Anti-Static Labels?
3 Steps to Select Anti-Static Labels: (1) Surface Resistance — 10^6–10^9 Ω (static discharge); (2) Triboelectric Voltage — <100 V (anti-friction electrification); (3) Decay Time — <2 seconds (rapid discharge). 3 Types of Materials: Permanent anti-static PET (most commonly used), removable anti-static film, composite multi-layer film. 3 Tests: Resistance Test (resistance meter) / Triboelectric Voltage Test (electrostatic meter) / Decay Time Test (charge decay tester). Consumer electronics do not require it; industrial electronics / PCB boards require it.
What chemicals do electronic product labels need to resist?
Class 3 chemicals must resist: (1) Cleaning agents—alcohol / isopropyl alcohol / acetone (wiping during production); (2) Flux—rosin / solder paste (splashing during PCB soldering); (3) Ink / coatings—cross-contamination from printed materials. 3 test methods: (1) Immersion test—label immersed in alcohol for 30 minutes, no peeling or discoloration; (2) Rub test—alcohol swab rubbed 100 times, text does not blur; (3) Print contact test—ink transfers onto label, text does not change color. PET film + modified acrylic adhesive offers the strongest chemical resistance.
How to test the performance of electronic product labels?
5-Step Standard Test: (1) Visual inspection – printing clarity + edge integrity + die-cutting accuracy; (2) Adhesion test – initial tack + holding power + peel strength across 3 dimensions; (3) Environmental test – high temperature 150°C for 30 minutes + low temperature -40°C for 7 days + humidity 90% RH; (4) Chemical resistance test – immersion in alcohol + acetone + flux; (5) Anti-static test – surface resistivity + triboelectric voltage. 3 testing tools: tensile tester (adhesion) + constant temperature and humidity chamber (environmental) + resistance meter (static). It is recommended that first-time suppliers must be fully tested, while established suppliers undergo random inspections on a quarterly basis.
How to Choose Materials for Electronic Product Labels?
Category 3 electronic products have different material requirements: (1) Consumer electronics (mobile phones/computers) — PET + permanent acrylic (medium performance, cost 0.3-0.5 RMB); (2) Industrial electronics (controllers/instruments) — PET + modified acrylic + matte film (high adhesion + chemical resistance, cost 0.5-1 RMB); (3) PCB/semiconductors — PI + silicone (extremely high-temperature resistant + chemical resistant, cost 1-3 RMB). 3 types not recommended: (1) Coated paper (not temperature-resistant or chemical-resistant); (2) Synthetic paper PP (not high-temperature resistant); (3) PVC (contains chlorine, partially banned in Europe and the US). It is recommended to first select the substrate according to product type and then select the adhesive according to process requirements.
