Do not use water to clean a no-clean soldered board unless the solder paste manufacturer recommends it, as it may result in a sticky, white residue on top of flux residues. This may impact electrical surface insulation resistance and corrosion. Do not use saponified water with no-clean unless the process has been tested for materials compatibility and subsequent corrosion. Surface insulation resistance (SIR) testing and electrochemical migration (ECM) testing are in order. Direct immersion should be avoided. Immersion can cause cleaning solvents and diluted flux residues to enter switch and other components. This, in turn, can result in an electrical short internal to the switch (from cleaning solvent conductivity), an open (from insulating flux residue), or corrosion (also from flux residue). Do not use ultrasonic cleaning. Even random-frequency or random-amplitude ultrasonic cleaners may impact certain devices that may be already mounted on the board (e.g., on the secondary side). Crystal oscillators are notoriously sensitive to ultrasonic cleaning. Other components have been known to fail as a result of ultrasonic agitation, which can damage or weaken internal bonds or die attach. After cleaning, use a microscope with as high a magnification as is needed to inspect for individual solder spheres from the paste. Ensure that solder spheres are not present; if they are, they should be in compliance with the workmanship standard. Also ensure that paste beads are not agglomerated in plated through holes, as they may interfere with PTH component insertion or press-fit operation. Generally a 30 stereo zoom microscope with good lighting is recommended for this inspection. If excess solder beads are still apparent, the board should be recleaned. Try rotating the board 90 or 180 for the repeat cleaning cycle.

The AVR processors are available many different pinouts, with different I/O resources, depending upon the number of pins in the particular processor. In some cases, you may feel the need for additional I/O pins than are available. There are many ways to expand the number of I/O pins with the help of shift registers or port expanders with a SPI or I2C interface. This section discusses means of expanding I/O. The primary requirement is that the I/O expansion scheme should have some serial format so as to take up minimum I/O pins on the processors. Serial Shift registers are great for such applications. Usually, these shift registers are of the serial-in and parallel-out or parallel-in and serial-out format, which suits our requirement. There are many bidirectional I/O expansion ICs with a 2-wire I2C interface available that are, of course, the best in terms of minimum pin usage.
