I saw this as a package type for an attiny microcontroller in the digikey catalog. I'm pretty sure that "QFN" stands for Quad Flat No leads. However, I'm not sure what prefixed "WF" means. Is there a ...
I have a QFN16 breadboard adapter and an ASXL335 chip, which I'd like to solder to it: However, the accelerometer chip has a central pad, while board does not. This causes an annoying problem of ...
I am designing a small PCB for mass production, and I am trying to keep costs low. One of the components is available in several different packages: 24QFN, 32QFN and LP (TSSOP 24 Pin). There is a ...
For a certain TI component, I'm choosing between these two packages, both of which are 24-pad and 0.5mm pitch: QFN: http://www.ti.com/lit/ml/mpqf167b/mpqf167b.pdf (4 x 4 mm) BGA: ...
Often a chip will be available in several different packages. Sometimes QFN which has a thermal pad, and TQFP which has no thermal pad. The justification for the thermal pad is that it helps conduct ...
