Product Details

Printed circuit boards are all around us. With this kit, students use photoengraving and chemical etching to generate their own printed circuit boards while learning valuable chemical concepts. The 100 mm x 150 mm copper boards are coated with a positive photoresist, which becomes soluble in basic solutions following exposure to light. Exposed copper is then removed through a redox reaction with iron(III) chloride.

Complete for 24 students working in groups of three. Additional presensitized copper circuit boards are available separately. An exposure source, developing trays and glass weight are also required to complete this experiment.

Performance Expectations

HS-PS1-2: Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.
HS-PS1-3: Plan and conduct an investigation to gather evidence to compare the structure of substances at the bulk scale to infer the strength of electrical forces between particles.
HS-PS2-6: Communicate scientific and technical information about why the molecular-level structure is important in the functioning of designed materials.
