If you have the right level of heat and good technique your board shouldn't get damaged, and the only thing that might be damaged is a component, but you can easily replace those for cheap online like tayda or someplace. The ones that look solid with very little solder are better done. The ones with gaps on the copper pad are poorly done. Its actually for fusing into a solid metal piece. What happens is the surface of the pin/wire/pad turns into a new material, so if that's a copper pad, the solder turns from 60/40 Lead/Tin to something/something/something Lead/Tin/Copper right near the surface.Ī misconception is that solder is some kind of cap or glue that holds two pieces of material together and is conductive itself. Enough heat and the solder literally melted into the wires and the pad. So the joints on the right are blobby and awful. The more you experience the less you'll worry about this because experience basically will hardwire the knowledge of "what should touch what". trace from the LED negative side, it goes right to the 4K7 resistor on the opposite side of the board. If you open the PDF and go to the picture of the green colored board with the red LED at the top, and trace the. Assuming the small curvy side of the LED is the anode lead (+) and the large flat side is the cathode lead (-), then the silkscreen on the PCB is correct, as is the orientation in the diagram in the PDF showing the long lead touching the square pad. The opposite lead of the 4.7K resistor should connect to a switch. The Negative lead of the LED should be connected to the 4.7K resistor. The positive lead of the LED should be connected, along with the 1n5817 diode, DIRECTLY to the Positive Supply Voltage. Okay so there is a 1n5817 diode, It should be connected parallel to the positive lead of the LED. Im assuming you're referring to the LED/diode symbol at the top center of the board between the positive and negative signs. I think they're indicating that the the positive side touches the square, the negative touches the circle. How did you come to this conclusion? Im looking at the orientation of the diodes all over the board, and they seem specifically oriented for their pear shapes.ĭ1-2-3-4 all have a square on the small side and a circle pad on the large flat side.
