The app allows you to manage traditional air conditioners that are controlled through infrared remotes. Designed for the office environment, the app relies on the ambient brightness (measured by Tibbit #28) to determine whether the aircon should be running or not. In the office setting, no lights = no people = no need for the aircon to work.

Tenting a via refers to covering via with soldermask to enclose or skin over the opening. A via is a hole drilled into the PCB that allows multiple layers on the PCB to be connected to each other. A non tented via is just a via that is not covered with the soldermask layer. Leaving these vias exposed or covered has pros and cons depending on the your design and manufacturing requirements.

Via in pad is the design practice of placing a via in the copper landing pad of a component. Compared to standard PCB via routing, via in pad allows a design to use smaller component pitch sizes and further reduce the PCBs overall size. With component manufactures pushing smaller parts every year and the demand from consumers for smaller devices, the usage of via in pad practices by hardware engineers have become more commonplace. In this article, we will discuss the differences between via in pad and traditional vias, when should you use via in pad, and how to design for it.

Take a few parts from the reel and look close at the parts to make sure the bottom surface of the leads is below the bottom surface of the body.

We are Currently running a Board and it seems that the SOT-223's on the bottom side have flux and water trapped under the part. Nothing has changed in our process and this is the only board that it is happening on. We are using Kester R562 water wa

Sounds like a flaw in your trap. It seams that during the pumping process the trap is ineffective or open, allowing normal sewer gases to bypass the trap and stink up your SMT area. This is similar to what happens when you do not use a drain for a lo

I agree with dave. Two things prevent oders from drains. The "P" trap and the celing or roof vent. If the system is sealed from the pump on then it should run thru a "P" trap this prevents vapors from comeing back thru the pipe. To make sure suction

No it's not a dry or defective trap. The exit line of the stencil sink is piped into a regular slop sink. There are no sewer gas smells coming out of the slop sink trap.

Maybe more baking time is needed. Topside board temp too low. Moisture trapped in board. Top of through hole capped by component and trapping flux. http://www.speedlinetech.com/electrovert/electrovert-troubleshooting/index.htm
