A regular PCB(print circuit board) has a lot of energetic and also easy digital parts that are attached to each other via slim copper traces. The energetic elements are the ones that utilize power to run, such as digital chips. The passive elements, on the other hand, do not call for outside power. Typical instances of passive parts are resistors and also capacitors. If a capacitor on a PCB spoils, it can be changed making use of some specialized devices.
SMD Capacitor Desoldering
SMD Adhesive is Surface Area Mount, there are 5 steps of desoldering the SMD PCB capacitor.
- 1. Transform the blowpipe on and also establish it to a temperature level of 370 levels Celsius.
- 2. Location the PCB on a level and also a completely dry surface area with the part side dealing with UP. Determine the capacitor to be desoldered.
- 3. Hold the capacitor by the center with tweezers as well as carefully touch among its firm ends with the idea of the welding torch. Maintain the idea there for 2 to 3 secs, and afterward rapidly relocate to the opposite of the capacitor and also maintain it there for 2 to 3 secs. Proceed this procedure till the capacitor comes loose, whereupon draw it out making use of the tweezers.
- 4. Location the copper pigtail in addition to among the pads where you have actually gotten rid of the capacitor as well as carefully press it with the suggestion of the welding torch. Maintain the idea there till all the solder change has actually been soaked up by the copper pigtail. Repeat this action for the various other pad.
- 5. Tidy the pads with an alcohol swab.

Normal Capacitor Desoldering
The desoldering ways of the normal capacitor is as follows.
- 6. Transform the blowpipe on and also establish it to a temperature level of 370 levels Celsius.
- 7. Area the PCB on a level as well as a completely dry surface area with the element side facing DOWN as well as recognize the pins of the capacitor that requires to be eliminated.
- 8. Location the copper pigtail at the joint of among the capacitor pins and also its equivalent pad and also delicately press it with the idea of the blowpipe. Maintain the idea there up until all the solder change has actually been soaked up by the copper pigtail. Repeat this procedure for the 2nd capacitor pin.
- 9. Transform the PCB over with the part side UP as well as carefully raise the capacitor with the help of tweezers. Do not make use of extreme pressure. If the capacitor does not appear conveniently, briefly touch its pins with the welding torch while drawing it out making use of the tweezers. This will certainly loosen up the solder bonds and also the capacitor will certainly appear.
- 10. Tidy the pads on both sides of the board with an alcohol swab.
