SMT fixtures are rigid PCB carriers that allow manufacturers to load single or multiple irregular boards, and then take them through the standard processing machines. This makes it possible to carry out tasks such as automatic mounting of electronic components, infra-red reflow soldering, wave soldering, automatic testing, etc.

The decoupling capacitors (C4, C5, C6, C7, C9, C10, C11) are arranged around the perimeter of the chip, very close to their respective power pins and to the vias that connect the caps to the internal planes. Notice how the smaller cap is always closer to the power pin; this is because we rely more on the lower-value capacitor for high-frequency bypassing, and thus the first priority is minimizing the inductance and resistance between the smaller cap and the pin.

Before you disconnect anything, make absolutely sure you know how to put it back. Number both sides of each connection with labels made of masking tape. If necessary, make drawings of cable routes and how clips fit. Use a craft knife or razor blade to cut away the wrapping from the damaged section. Take care not to cut into the plastic cable insulation.

Since the finite-impulse-response (FIR) filtering is a common operation in DSP, we will continue our discussion based on examining the difference equation of an FIR filter. This simple example will show the typical properties of many DSP algorithms. After reviewing the problem of handling the incoming samples, we will discuss the circular buffering as an efficient solution to the problem.

Panelization is the arranging of arrays of multiple PCBs onto a single substrate that fits in the standard processing machine. A panel may hold multiple boards with similar or different sizes and shapes. This method is faster and less costly compared to the fixtures, which require a custom carrier for every new PCB design.

Care should be taken when depaneling the perforated-tab PCB array; otherwise, an incorrect method will splinter or tear the solder-mask or active surface layer. The ideal breakout method should not cause any damage to the board or transfer stress from the PCB surface to the components.

However, and this is very perplexing, there is no additional information related to the "separate application note." My suspicion is that Sensirion intended to include a link to this app note but then simply forgot to include it; perhaps additional information will be provided in the datasheet next revision.
