Kit Notes (cont.)
your soldering iron tip to the pre-soldered pad to reflow the solder. Then you
can solder the other side normally.
• Flux is your friend. Use flux. Water-soluble flux is best for a clean finish, but
you have to make sure to get it all off when done, as it can corrode the joint
and some fluxes may also be capacitive. You can also use no-clean flux.
• Smallest first. Solder the components in increasing order of size.
• Minimize heat exposure. Heat destroys components, and SMD are particularly
sensitive because they have less mass to distribute the heat. Flux helps with
this too.
• Use the face plate to line up the potentiometers,jacks, and LEDs, before
soldering; this is much easier than resoldering them to line them up correctly
afterward. You may have to attach and remove the panel a few times with this
kit because of the component density.
Assembly Order
The easiest build order is as follows:
1. All SMD. For the rest, follow the order shown on Page 7:
2. Install & solder the rear chaining header.
3. Install & solder the potentiometers, switches, and LEDs. Trim the LED
leads.
4. Assemble the regulators and heat sinks (see graphic, p.9), then install
them on the PCB. Install & solder the quick-connect tabs.
5. Install & solder the 2x8 shrouded headers. NOTE THE ORIENTATION.
Due to the cramped board layout, there wasn't enough room for the
CV and Gate pins, so they have been removed from the headers (see
graphic p.5).
6. Install & solder the jacks.
7. Attach the panel - see toggle switch jam nut instructions on p.14.
Help
If you're still having problems, email me! I am always happy to help. When
emailing, please include high-resolution pictures of your circuit boards.
Most of the troubleshooting requests I have received were solved by zooming
in and closely examining the pictures. Cold solder joints are sneaky and hard to
spot if you haven't dealt with them before. A cold solder joint is where the solder
doesn't adhere to both the pad and the component lead, and just flowed around
one of them without making contact. They happen, and they suck, but they're easy
fixes once you find them.
