Common methods of making PCB boards (1)

The fixed socket of round push-pull self-locking connectors created by xi’an spring technology co,.ltd are for the most part utilized for PCB board establishment. Coming up next are a few techniques for making PCB sheets gathered by xi’an spring technology co,.ltd:

Production method one:

  1. Slice the copper-clad board to the size required for the circuit chart.
  2. Put the wax paper on the steel plate, utilize a pen to imprint the circuit outline on the wax paper at 1:1, and cut the circuit chart engraved on the wax paper as indicated by the circuit board size, and spot the cut wax paper on the printed copper board. Take a limited quantity of paint and powder to make a thick and appropriate printing material. Plunge the printing material with a brush and apply it equally to the wax paper. Rehash a few times to print the circuit load up. This generalization can be utilized over and over, reasonable for little group creation.
  3. Set up a destructive arrangement with a proportion of 1 g of potassium chlorate and 40 ml of hydrochloric corrosive with a grouping of 15%. Wipe the consumed zones on the circuit board for erosion.
  4. Wash the consumed printed board over and again with water. Wipe off the paint with banana water and wash it a couple of times to make the printed load up clean without leaving destructive fluid. Smear a layer of rosin arrangement and dry the opening.

Production method two:

  1. Printed board chart. The cushions in the figure are spoken to by dabs, and the wiring can be a solitary line, yet the position and size must be precise.
  2. As indicated by the size of the printed board, cut the printed board and clean the copper foil.
  3. Use carbon paper to duplicate the image to the printed board. In the event that the circuit is basic and the maker has some involvement with board making, this progression can be precluded.
  4. Glue the standard pre-cut images (cushions) with various inward and external distances across as per the genuine states of the segments; at that point glue tape lines of various widths relying upon the current size. For standard pre-cut images and tapes, they are accessible in electronic stores. The regular details of pre-cut images are D373 (0D-2.79, ID-0.79), D266 (0D-2.00, ID-0.80), D237 (OD-3.50, ID-1.50), and so forth. It is ideal to purchase paper-based materials (dark ), do whatever it takes not to utilize plastic-based materials (red). The regularly utilized particulars of tapes are 0.3, 0.9, 1.8, 2.3, 3.7, etc. The units are all in millimeters.
  1. Tap the sticker with a milder sledge, for example, smooth elastic or plastic, to make it completely cling to the copper foil. Concentrate on striking the turns and laps of lines. At the point when it is cold, it is ideal to utilize a warmer to warm the surface to improve the attachment impact.
  1. Put into ferric chloride to erode, however please note that the fluid temperature isn’t higher than 40 degrees. After erosion, it ought to be required some investment, particularly if there is a flimsy line.
  1. Enlightening, clean the copper foil with fine sandpaper, apply rosin liquor arrangement, and dry it to wrap up. The nature of this printed board is exceptionally near the customary printed board. 0.3mm tape can be passed between the two feet of the IC, which can significantly lessen the short jumper on the facade of the load up to spare difficulty and time. I regularly utilize this technique in my work to make exploratory printing plates or a modest quantity of items.

Production method three:

  1. Disintegrate one bit of varnish (ie shellac, accessible in synthetic crude material store), break up in three pieces of total liquor, and mix appropriately. After every last bit of it is broken up, include a couple of drops of clinical purple medication (gentian violet), Make it seem a specific shading, in the wake of mixing equitably, it tends to be utilized as a defensive paint to portray the circuit board.
  2. First clean the copper plate with fine sandpaper, and afterward utilize the duckbill pen (or the ink duckbill pen used to draw illustrations on the compass) in the attracting instrument to draw. The duckbill pen has a nut to change the thickness of the stroke. The stroke thickness is flexible, and straight lines and triangle rules can be utilized to draw exceptionally thin straight lines, and the lines drawn are smooth, uniform, and without edge serrations, giving a smooth and familiar inclination; simultaneously, it can likewise be utilized on the circuit board. Compose Chinese characters, English, Pinyin or images in the free space.
  3. On the off chance that the line drawn is drenched around, the fixation is excessively little, you can include a little paint; in the event that you can’t drag the pen, it is excessively thick, and you have to include a couple of drops of outright liquor. It doesn’t make a difference if the depiction isn’t right, simply utilize a little stick (matchstick), make a little q-tip, plunged in a little supreme liquor, you can without much of a stretch wipe off, and afterward re-draw. When the circuit board is drawn, it very well may be consumed in the ferric chloride arrangement. After the circuit board is all around eroded, it is likewise advantageous to evacuate the paint. You can clear off the defensive paint with a cotton ball dunked in anhydrous liquor. After a touch of drying, you can apply pine fragrance.
  4. Because of the quick dissipation of liquor, the readied defensive paint ought to be fixed in a little jug, (for example, an ink bottle). Remember to close the top after use. On the off chance that the focus gets thicker in the following use, simply include Just include a suitable measure of outright liquor.
