Become Expert In Laptop Motherboard Repair

5 steps to remove ic chips from the motherbaord

1. Heat surface mount resistors, transistors, diodes, with a miniture hot air blower or heat gun for 60 seconds.
2. Pull the ic chip from the motherboard.
3. Clean the contact area using a solder flux mix place a small drop on the contact area.
4. Place the component on top and then reapply heat with your blower or heat gun.
5. Clean with alcohol....done.

How do you test a transistor using cathode ray oscilloscope?

It's possible to test the transistor using Cathode Ray Oscilloscope (CRO)
CRO provides a function called "Component Testing". Just connect the transistor terminals between two pins provided by this function and you can observe the patterns on the CRO screen. Normally, in case of transistor, The operation is divided in few parts.
01. Observe the pattern for CB configuration.
---- For this, connect the terminals from CRO between this Collector and Base terminals and you can observe the pattern shown by CRO.
Same procedure should continue for CE & BE configuration so as to test the transistor.
