An easy way to mount DS18B20 temperature sensors

ds18b202-600

Matt wrote an article describing a technique he used to mount DS18B20 temperature sensors:

One of the biggest advantage of these sensors over I2C sensors, is that you can mount them almost anywhere. That having been said, I’ve never quite managed to come up with an elegant solution, particularly when attaching to a heatsink (for cooling applications)

EAGLE: Panelizing made easy

mousebite

Sjaak shared a tip for panelizing PCB boards in Eagle:

Panelizing is done by machining a slot between two or more boards, but keep them attached by a small amount of PCB material (mousebites). I used to do it by hand: generated all the schematics into multiple sheets and then route the board and finally add the slots with mousebites in the PCB editor. I generally use slotwidth of 50 mil and the smallest drill possible (12 mil) 12.5 mil apart as breakingline. I tend to place the mousebites about 2cm from each other to maintain PCB strength.

The handy feature I found is in the PCB editor (schematics has one too!) is to import an other PCB design. First you design the boards individually and then import them all into an empty board file and place them 50 mil from each other, add mousebites to taste and send them off 🙂

Soldering TQFN with a distance

Here is my solution to this problem. First clamp the Ic to vise or ask your wife to hold the tweezers with the chip
Next, use your sharpest soldering tip and apply some solder to the pads. Please keep in mind the chip has 0,5mm raster between pads.
After soldering all 10 pads it should look something like this
Now place the chip on the PCB and position it correctly – check the orientation. The height of the solder applied to the chip pad will keep the thermal pad away from the traces under the chip. Place soldering tip close to the chip at one pad and heat it up until solder flows from chip to the PCB pad. Don’t push the chip down! Check the position of the chip and repeat this for all pads at one side and then repeat for the rest of the pads
