Silk Screen Printing Circuit Board and Signage Panel Method The most intractable thing for electronics enthusiasts and scientific and technical personnel in the development and production of electronic products is how to rapidly mass produce good quality circuit boards and signs and panels. Because the external processing has certain requirements in quantity, and the price is expensive, the quantity is not suitable for external processing. For this reason, this article introduces the reader to his own method for mass production of circuit boards, panels, and signage.
First, the production of materials
1. A rectangular box of 30cm x 23cm is nailed with a square bar with a section of 3cm x 3cm.
2.200～300 mesh screen
3. Diazo photosensitive adhesive
4. Laser typing film (polyester translucent film)
5. UV lamp (or other light source)
6. Hair dryer
7. Triangle (plastic or stainless steel)
Second, the production of circuit boards
1. Use circuit design software (PROTEL) to design the circuit diagram and use a laser printer to print on the A4 laser marking film.
2. Manually tighten the screen on the wooden frame, and then use a special nailing machine or glue to fix the screen on the wooden frame. Then use a detergent or detergent to wash off the oil and blow dry.
3. Photosensitive adhesive: Use a triangular plate (plastic) or a flat hair brush that does not lose hair to apply the photo sensitive adhesive to the screen, and evenly squeegee up and down. Do not pause during the movement so that the photo resist can be evenly applied to the screen. The screen surface on the inside of the general frame can be scraped twice, and the side of the screen touching the substrate can be scraped three times, but remember that after each squeegee application, the hair dryer is used to apply the bake-out conjunctiva and then the blade is applied a second time.
4. Drying: The drying temperature is preferably 30 to 40°C, and preferably 30 minutes or less. If the temperature is too high, the conjunctiva is too fast, and if the temperature is too low, the photosensitive time will be prolonged and the development will be difficult. The drying time and temperature have a close relationship with the quality of the platemaking and should be strictly controlled.
5. Shaiban: the light source should use ultraviolet light source, 20W ~ 40W lamp array spacing of 3 cm, the light source from the layout of about 15 cm, the photosensitive time measured by the light source strength and weakness.
6. Development: Photosensitive plates are immediately immersed in warm water for about 2 to 3 minutes. After immersion, they are rinsed with a water gun (it can also be soaked with developer for 20 to 30 seconds).
7. Blow dry quickly: Place the developed plate flat. Use a fan to quickly dry the pattern. The fan is about 20 cm away from the layout.
8. Printing plate repair: printing plate repair is one of the processes must be carried out, but also an effective guarantee of product quality, repair, oily version of the oil used sexy plastic, sealing mesh can be.
9. Secondary sensitization: After the second sensitization, the purpose is to enhance the cross-linking fastness, harden the film, and the operation method is the same for the first time, the time is 12 to 15 minutes, and the sun is 7 to 10 minutes.
10. Printing: Put the cut copper plate on the wire plate. The pattern on the net is aligned with the copper plate. Use a quick-drying, anti-corrosion printing material to pour it onto the wire mesh. Then use the triangle plate to scrape on the wire mesh. You can get the same graphics as the original on the copper plate.
11. Corrosion: The copper coupons were etched in ferric chloride solution.
Third, the production of panels, signs
1. Use a drawing software to design a panel and a signage plate, and use a laser printer to print on the laser typing film of A4. The screen production method and the circuit board production method are the same.
2. Printing: Put the PVC board, metal board, sticker, and plastic shell under the wire mesh and pour the printing ink (different materials with different inks) onto the wire mesh, then use the triangle board to squeak the wire up and down. You can get the same panel and signage as the original artwork and text.
Fourth, printing
The circuit board and the panel, the signage diagram are made in a net frame, and printed separately, and the panel signage diagram is printed on the plastic transparent tape when printing the circuit diagram, and the circuit diagram can be glued when the panel is printed, so that the circuit diagram and the panel can be arranged at one time. Signage is done at the same time, which is very convenient for electronic enthusiasts.
The above inconvenient to make the circuit diagram can be sent to the manufacturers by e-mail, a screen of 30cm × 23cm production of about 45 yuan (equivalent to the same area of ​​the price of the photosensitive circuit board).
