How to realize the production of Arduino development board, in view of this problem, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible method.

Arduino UNO introduction

, Arduino development board production

Tutorial: Arduino production

Arduino UNO figure what is Arduino? Arduino is a convenient, flexible and easy-to-use open source electronic prototype platform. Includes hardware (various models of Arduino boards) and software (Arduino IDE). Built on.

Arduino production material

Tutorial: Arduino production

Materials are all kinds of components, component list, components purchase Taobao

Arduino production tool

Tutorial: Arduino production

Production of Arduino-related equipment, tools and consumables equipment inkjet printers such as MP280 paper cutter square box drill + tungsten steel bit hot air gun electronic scale soldering iron + solder wire film photosensitive ink + diluted water developer environmental protection etching agent.

Arduino Film Printing

Tutorial: Arduino production

The purpose of PCB printing is to print the negative (that is, reverse color) of the circuit diagram to the film film. The PCB printing process opens the Eagle software to import the Arduino UNO schematic diagram in the left toolbar of the eagle software, click wire to draw the line, and Docum... on the 48th layer.

Arduino PCB photographic plate

Tutorial: Arduino production

The purpose of the production of the photosensitive plate is that the copper clad plate is coated with photosensitive blue oil, which requires that the schematic pattern of the film film is exposed and covered on the photosensitive board. The photosensitive plate production process is configured with a ratio of photosensitive blue oil to diluent at 5:1 with a brush coated with copper in one direction without breaking the wire.

Arduino PCB exposure

Tutorial: Arduino production

The exposed blue oil for the purpose of exposure will slow down the reaction with the developer, using this principle to print the circuit diagram on the film on the copper clad laminate. Exposure process homemade photosensitive box, 2 ultraviolet lamps away from the bottom 8cm-12cm dried copper plate and printed film film.

Arduino PCB development

Tutorial: Arduino production

The PCB developer washes away the blue oil from the unexposed part and prepares for etching. The ratio of developer to water in the PCB development process is as follows: 1 the ratio of developer to water is 10 seconds, regardless of whether the developer is developed or not, and develop bit by bit with a small brush. Cooperate.

Arduino PCB etching

Tutorial: Arduino production

Reaction of PCB etching solution to exposed copper not covered with blue oil the ratio of etching agent to water PCB etching process load a large basin with hot water at 3:10, then heat it in a small basin containing etching liquid, and finally put into copper clad laminate etching for 5 minutes.

Arduino PCB delamination

Tutorial: Arduino production

PCB film removal purpose to remove the blue oil on copper clad laminate PCB film removal process the ratio of film remover to water is 1:70. Soak for 10 minutes and start to remove the film. Arduino development board can be made and cleaned with disposable chopsticks. After removing the film, Arduino development board production, from left to right to test the two adjacent lines are not short circuit, there are short.

Arduino PCB heat transfer text

Tutorial: Arduino production

PCB thermal transfer text purpose marking important and pin and logo PCB thermal transfer text flow use windows built-in drawing software to process (delete unwanted text), use a laser printer to print characters onto thermal transfer paper and cut to the right size, and board weight.

Arduino PCB greased

Tutorial: Arduino production

The role of PCB green oil is anti-welding, anti-rust PCB green oil process first apply some green oil in the middle, and then cover it with a film, and finally use a waste bank card to scrape evenly the protective film of the dry film used by the store to cover the green oil, and the protective film of the waste mobile phone film can also be tested personally. Ferrin film. No.

Arduino PCB drilling

Tutorial: Arduino production

PCB drilling process 0.3mm through the hole can use resistance pins, 0.5mm through the hole with 0.5mm brass tube, cut with nail Clippers. The drill bit should be made of tungsten steel. Shake the drill bit after installation to see if it is loose. Drill a hole in the blank space on the edge of the board and measure if it is crooked.

Arduino PCB welding

Tutorial: Arduino production

* * PCB welding process * * first weld the minimum system, and then weld the rest after welding, clean with board washing water, wipe with paper towels while smearing board water * * PCB welding diagram * *

Arduino PCB burning

Tutorial: Arduino production

PCB burning purpose 16u2 and 328p chip must be written into the boot program to run normally PCB burning process welding 16u2 and 328p minimum system (VCC/GND/ crystal oscillator) 1, test VCC and GND without short circuit, can be plugged in.

Arduino UNO test

Tutorial: Arduino production

UNO test flow finished welding USB interface part of the circuit 1. Plug in the USB interface, find "Arduino Uno" in other devices in device Manager, right-click to update the driver, and then manually update to Arduino IDE's drivers file.

Summary of Arduino production

Tutorial: Arduino production

The difficulties in making Arduino double panels are as follows: 1. Alignment of positive and negative sides of double panels and welding 16u2 chips.

This is the answer to the question about how to make the Arduino development board. I hope the above content can be of some help to everyone. If you still have a lot of doubts to solve, you can follow the industry information channel to learn more about it.
