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.
The students has access to a huge range of tools, software including business and web design software. We also have links to laptop and PC suppliers, parts and accessories in the UK and USA
Advance Chip-Level ModuleChip-level Training will be customized for your present knowledge of electronics. If you go through the fundamental track , all the power electronic components will be introduced before we move to the logics section. After you become comfortable with power electronics the logic session follows . It is an intensive coverage into the intricate details of chip-level service of the laptops. This involves detailed circuit tracing , signal analysis , replacement of SMD devices and all the tips and tricks our service engineers acquired from the years of experiences. the session makes you confident enough to chip-level service the new generation notebooks from Lenova , Compaq, HP , Toshiba ,Sony and the like .
