BGA andSMT inspectionis one of the toughest jobs. It becomes extremely difficult to inspect the BGA joints since the solder is underneath the BGA Package and are not visible. The only satisfactory means of testing BGA Solder Joints is X-rays.X-Rayhelps to see the joints underneath the packag...
A reset does not always provide a satisfactory solution. Samsung dishwasher won’t turn on As previously said, if your dishwasher would not turn on at all, it ismost likely because of a wiring problem. If you believe there is an issue with your dishwasher installation, contact a professional...
Another danger of black solder mask is the way it absorbs heat during reflow. You must scale down the configuration file or make sure the temperature sensor is always placed on the board. Screen printing also tends to turn light brown during the reflow process, which may be because the circ...

This is achievable for a wide variety of amplifier implementations, but individual noise sources must be tracked during amplifier design to ensure a satisfactory overall SNR.Distortion mechanisms: These include nonlinearities in the modulation technique or modulator implementation—and the dead time used ...
Also called “frequency response,” bandwidth is the range of frequencies within which a signal amplifier’s performance is thought to be satisfactory. This has historically been accepted to mean that it can reproduce the signal up to the point where the signal’s amplitude is still within -3 ...
A bewildering array of CAD programs are available, ranging from free downloads to highly sophisticated products with immense capabilities, (and substantial price tags.) The free programs provide basic 2D drafting capabilities, with a few offering 3D. These are satisfactory for the hobbyist who inten...
It is necessary to ensure that once the solder joint has been made that it is satisfactory. This is best done by visually inspecting it.Check for sufficient solder: Solder joints should have sufficient solder but not too much. For printed circuit board or PCB solder joint, the solder should...
