GrubDAC Step-by-Step

1. Solder PCM chip anchor points -
Both corners are needed to keep the chip from rotating when soldering. Anchor points are on the bottom and top rows, allowing free soldering for the left and right side pins in Step 2 below.
2. Solder PCM chip left and right side pins -
Warning! make certain the locating dot on the chip is oriented as indicated in the layout and on the PCB silkscreen. Refer to the build-by-photo pages for details on soldering the pins.
3. Solder PCM chip top and bottom row pins -
Both corners are needed to keep the chip from rotating when soldering. Anchor points are on the bottom and top rows, allowing free soldering for the left and right side pins in Step 2 below.
4. Solder Wolfson chip anchor points -
Both corners are needed to keep the chip from rotating when soldering.
5. Solder Wolfson chip pins -
Warning! make certain the locating dot on the chip is oriented as indicated in the layout and on the PCB silkscreen. Refer to the build-by-photo pages for details on soldering the pins.
6. Apply solder to remaining SMD anchor pads -
If you're right-handed, place the solder on the right side pad. This allows you to re-melt the solder with the iron in your right hand, while positioning the part with tweezers in your left. For vertically-oriented parts, pick the top pad and rotate the PCB 90 degrees clockwise to solder the part.
