It only takes one minute to make a PCB in this way!

Although online PCB manufacturing is very fast and cheap now, some manufacturers even provide free test board manufacturing, but compared to "one minute manufacturing" to make test circuit boards, it takes too long to send out the board.
For the circuits that need to be tested, through rapid plate making, you can quickly iterate to complete the experiment of the experimental circuit. The final official circuit board can be handed over to a regular manufacturer to help make it.
I.C.T is a manufacturer of SMT machines. It mainly provides customers with SMT production lines including SMT Stencil Printers, Pick and place machines, Reflow Oven, AOI Machine, Wave Soldering Machine and PCB Handling Machine etc.

The following shows the specific process from rapid plate making to the completion of the welding test:
1. Draw the PCB circuit board:
2. Set to print only TOP LAYER and via layer
3. Use a laser printer to print on thermal transfer paper
4. The thinnest electrical circuit set on this circuit board is 10mil
5. The one-minute plate-making time starts when the laser printer prints the black-and-white image of the electronic circuit on the thermal transfer paper.
6. For single-sided circuit boards, only one is enough.
Then attach it to a copper-clad laminate of a suitable size, and heat and press the heat transfer machine to complete the heat transfer in 20 seconds. Take out the copper clad laminate and uncover the thermal transfer paper, you can see the clear circuit diagram on the copper clad laminate.
7. Then put the copper clad laminate in the oscillating corrosion tank, using a mixed corrosive solution of hydrochloric acid and hydrogen peroxide, it only takes 15 seconds to remove the excess copper layer.
The proper ratio of hydrochloric acid, hydrogen peroxide, and a high-speed oscillating corrosion tank are the keys to achieving rapid and perfect corrosion.
After flushing with water, the corroded circuit board can be taken out. A total of 45 seconds passed at this time.
Never touch high-concentration corrosive liquids recklessly. Otherwise, the pain will be remembered for a lifetime.
8. Use acetone again to wipe off the black toner. In this way, an experimental PCB board is completed.
9. Apply flux on the surface of the circuit board
10. Use a wide blade soldering iron to tin the circuit board for easy soldering later
11. Remove the soldering flux and apply the soldering flux to the surface mount device to complete the soldering of the device
12. Because of the pre-coated solder, it is easier to solder the device
13. After soldering, clean the circuit board with washing water
14. Part of the circuit board
15. There are multiple short wires on the circuit board
16. The short wiring is completed by 0603, 0805, 1206 zero ohm resistors
17. After ten minutes, the circuit board is ready for experimentation
18. Circuit board under test
19. Complete circuit debugging
The one-minute thermal transfer plate making method can make the production of hardware as convenient as software programming. After the circuit block test is completed, the production of the circuit is finally completed using the formal plate making method.
This method not only saves the cost of the experiment, but more importantly, it saves time. A good idea, if you wait a day or two to get the circuit board according to the normal plate-making cycle, the excitement will be consumed.
