The Electronic Systems: Surface Treatments & Finishes A1 poster is an engaging and informative classroom resource that introduces students to the methods used to protect electronic and mechanical components from corrosion, wear and friction. Ideal for Design & Technology and STEM learning, this poster breaks down key surface treatment processes in a clear, accessible way.

Learners explore how PCB lacquering (conformal coating) protects printed circuit boards from moisture, dust, extremes of temperature and chemical exposure. The chart explains how lacquer appears under UV light during quality control, helping students understand real industrial inspection methods.

The poster also covers lubrication, explaining how oils, greases and dry lubricants like graphite reduce friction between moving parts. Real-world examples—such as hinges, bearings, gears and locks—illustrate how different lubricants are used across electronic and mechanical systems, improving efficiency and reducing wear.

Bright images, colour-coded sections and concise text make this poster ideal for lesson delivery, revision and project support. Its large A1 size ensures that every detail is readable from anywhere in the classroom, making it an excellent long-term reference display.

Important Update on Lamination:

We are transitioning to a new, thinner lamination as part of our supplier’s commitment to sustainable and cost-effective production. While you may receive a mix of older and newer laminations during this period, rest assured that both versions maintain the same high-quality standard you expect from Daydream Education.

We appreciate your feedback on the updated lamination to help us refine this change. Feel free to share your thoughts—we value your input!

Thank you for supporting our move towards more sustainable practices.
