&3. For positioning, first use a soldering iron to melt a little solder to one of the soldering points, then use tweezers to pick up the chip resistor and capacitor and place them on the soldering point, then use a soldering iron to melt the solder just added so that one end of the resistor and capacitor is first Solder and fix the resistors and capacitors. Note: The resistor and capacitor should be placed exactly in the center of the two soldering points. If the error is relatively large, use a soldering iron to melt the solder again and fine-tune the position of the resistor and capacitor so that they are aligned with the center. 4. For soldering, first melt some solder to the top of the soldering iron tip, and then contact Ouyang: You can get free sample delivery service. You are always welcome to call and go to another section of the soldering point.
5. Retouching After welding the resistors and capacitors, observe whether the welding points are qualified and beautiful. If it is not beautiful, it should be soldered again, and the right amount of rosin should be applied to the spot to make the solder surface rounded.
Chip capacitor is the Chinese abbreviation of multi-layer (laminated, laminated) chip ceramic capacitor, and the English abbreviation is. When chip capacitors are subjected to temperature shock, cracks are prone to occur at the front end of the solder terminal. Contact Ouyang on this point: Free sample delivery service is available. Your call is always welcome. The performance of small-scale capacitors is better than that of large-scale capacitors. The principle is that the heat conduction of large-scale capacitors does not reach the entire capacitor so quickly, so the capacitor The temperature difference at different points of the body is large, so the expansion magnitude is different, thus generating stress. This is the same as when boiling water is poured into a thick glass, it is more likely to break than a thin glass. In addition, 2. The welding methods for identifying chip resistors and capacitors are roughly the same, and the welding points are also very similar. They are two flat contact points, but there is a white line in the center of the contact point of the capacitor to distinguish the welding of the resistor. point. Chip resistors and capacitors are very small in size, some are only as big as two or three hairs, while chip resistors are as large as two or three hairs. Resistors are usually black, and there are corresponding numbers on the reverse side to represent their standards. There will also be corresponding markings on the circuit board to mark its location. If you contact Ouyang at the corresponding resistance welding: you can get free sample delivery service. Your call point is always welcome. There is an R+number&r next to it, just put it on the corresponding welding point. This resistor has no positive or negative polarity, but the chip capacitor is not necessarily positive. Chip capacitors without negative electrodes are usually small squares, and all four sides of them can be patched for soldering. Capacitors with positive and negative electrodes are relatively large. The capacitor only needs one welding surface and is marked with a deep line on the reverse side.
