To completely realize the situation, we need to know very well what makes up a rosin that is typical solder fume. A solder that is typical is a mix of really small particles (smoke) and gases which may be explained as around 95percent particulates (the physical smoke plume), and around 5% gases and vapours that may contain a cocktail of Acetones, Methyl Alcohol, Formaldehyde, Carbon Dioxide, Diterpine Acid, Carbon Monoxide and Isopropyl Alcohol. Note: Even 'Synthetic' and 'No Clean' fluxes can cause lung irritation that is serious
As soon as inhaled, the lungs cannot easily remove particle sizes under 10 microns. If you knew a human being locks is approximately 100 microns in diameter, consider this - the greatest solder fume particle is just about 10 microns in diameter therefore the smallest is about 0.3 microns (you can simply see 30 microns having a naked attention).

Situation 3: Dell e151fp ( equivalent to Acer Chassis that is FP553 power or power on then shutdown shortly
Solution 3: Solder out the faulty C605, C707, C703 capacitor, the faulty power UC3842B that is ic resistors R613, R623, R615, defective transistor Q601, faulty diode D604= 1N4148 and fuse F601. Solder the parts that are new in to the circuit.
From above examples, in spite of how severe fault degree of lcd monitor, the soldering work is always associated with repairing lcd monitor. There is the next articles explain the basic soldering to advance soldering technique of the surface mounted devices (SMD) on our website.
