There are many PCB design software available in the market, also named EDA software (Electronic Design Automation). Choosing one or another can depend on the printed circuit board design necessities the designer has and the price he can or want to spend. The election can also depend if the designer is working as a hobbyist, a freelance or if he is involved in a big company. In the last case, sometimes the designer has not any [Read more...]
Following the previous post in which we explained what is a list of materials and how to export this file from the main PCB design software was described, in this post we continue explaining other file required when you want to assembly your PCBs in pick and place machines that is the CPL file.
CPL is the acronym of Component Placement List. It is possible to export it from any printed circuit board design software and contains the exact position in [Read more...]
BoM is a word very used in electronics. It is the acronym of Bill of Materials and it is a list with all the components and detailed information of them, that compose an electronic and that are required to build the products.
It is very useful to provide the correct information about the components that will be soldered in a PCB and to have a record of all the components that are required to be procured or used from an internal inventory. [Read more...]
FR4 is a printed circuit board based on glass-reinforced epoxy laminate material. It is the most used material because it is cheap in comparison with other materials and it can be used in many applications. [Read more...]
Printed circuit boards are composed by substrate and layers of copper foil. When the PCB is single layer, the copper foil will be only placed in the top or the bottom of the PCB, and when the board has two layers, the PCB will have copper foils in both top and bottom sides.
Typically, the thickness of the copper layers is specified in copper weight with oz/ft2, but commonly is named only as oz. But also, sometimes, it is specified in length, in µm, following the relationship that 1 oz/ft2 is equal to 17.5 µm. [Read more...]
