With the Make a Printed Circuit Board Student Laboratory Kit, electrify your redox lessons with printed circuit boards! Students will use photoengraving and chemical etching to generate their own printed circuit board. Students design their own works of art while learning valuable chemical concepts!
This item can only be shipped to schools, museums and science centers
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. Transparancies are included to print or create needed designs. In order for the images to transfer correctly, they need to be in black and white (no gray) and printed using a laser printer at a resolution of 600 dpi or higher. Ink jet printers will not work.
Materials Included in Kit:
Iron(III) chloride, 500g
Sodium silicate, meta, 100 g
Foam brush, 2", 8
Forceps, polypropylene, 5½", 8
Presensitized PCB 100 x 150, 8
Transparancy sheets, 6
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.
