such as mobile phones), are often abused. In addition to collecting dust and dirt that seeps into phone cases, e-book readers, and similar handheld devices PCBs are known to be immersed in and splashed from liquids during everyday use. As a result, the service industry has emerged to ...
Soft soldering is a technique used to join wires, fix electronic components onto circuit boards and bond copper pipes together. This tutorial shows you how to solder step by step.
If they quote the quantities of various minerals in parts per million (PPM), you can easily work out the conversion of PPM to grains per gallon (GPG) by dividing the quantity of PPM by 17.1. If your water is supplied privately, you’ll have to test for hardness yourself. In some ...
The Ultimate Test of a Long Term Partnership How Charlotte Water and Synagro Partnered to Safely Manage Solids Contaminated With Polychlorinated BiphenylsOn Thursday, February 6, Mallard Creek WRF was contaminated with high strength polychlorinated biphenyls (pcbs) and Trichlorobenzene (tcb). On February...
However, majority of printed circuit boards (PCBs) usually fail the last test. When this issue happens, performing a reliable electronics failure analysis so as to get precise and clear detains regarding the problem source, and to make sure that the problem doesn’t arise again. ...
materials used in PCBs are susceptible to the formation of water molecules. Additionally, PCBs that have been produced and stored for a certain period may absorb moisture from the environment. “Water” is one of the main culprits of PCB delamination or popcorn, and it also contributes to ...
In today’s era of electronic devices, PCBs remain an important part that keeps these equipment and machines working. You can now see jam-packed PCBs everywhere from your LED bedside lamp to laptops. But, we will not go too deep about the different kinds of PCBS and what they are used ...
As you can see, in this application too the transistors is basically amplifying the tiny base voltage such that a bigger load at its collector could be switched ON. The LDR can be replaced with other sensors such as athermistorfor heat sensing, awater sensorfor water sensing, aphotodiodefor...
Cleaning a PCB with a solvent like IPA should only be done in a well vented environment, ideally under a fume hood. Demineralized water can be used as an alternative. Be sure to remove any excess moisture and properly dry the board (a few hours in a low-temperature oven can effectively ...
Use of a more aggressive solder paste, like a halide containing water soluble, may enable soldering to the oxidized leads. Tony Lentz Field Applications FCT Assembly Tony has worked in the electronics industry since 1994. He worked as a process engineer at a circuit board manufacturer for 5 yea...
