Oxidation and corrosion are very important problems that can affect to the performance of printed circuit boards. In next paragraphs some advices will be given to avoid that the PCBs you request to your manufacturer do not suffer these problems and also some tips about how to avoid them also with time are described.

When you design your PCBs and send them to manufacture, you have to provide to the manufacturer your design in a correct way they can do the work. You will have to put all your designs in a panel so they can build them.
When you request PCBs, the manufacturer will use a panel of the material you will request. There are different sizes of panels, but you will have to take into account that, typically, independently of the units you require, at least you will pay the price of a panel. [Read more...]
Solder paste is a mix of different components used to solder SMD components. Unlike solder wire, that is commonly utilized with solder pencils, solder paste is used when reflow techniques are performed. You can find it typically in jar or syringes depending on the quantity you will need. [Read more...]
BGA is the acronym of Ball Grid Array. In this kind of devices, the bottom of the package is composed by different pads with solder balls distributed in an array. It is a more or less a recent technology that appeared to increase the number of pads per size of package with respect older ones. It is very useful for digital circuits like FPGAs in which a high density of signals is required. It allows to concentrate more functions of the ICs using the minimum room in the PCB. It has some advantages and some disadvantages with respect other packages. [Read more...]
In order to solder SMD components in a PCB you can use different equipment but, depending on the component to be soldered, not all the tools can be used. For each equipment, some rules should be used to obtain the best result and avoid future problems in the electronic circuits.
Main equipment that can be used to solder components are soldering irons, soldering stations, hot-air stations, hot plates and solder reflow ovens. [Read more...]
