Other Parts Discussed in Thread: TPA3106D1

For an intercom we plan to use the TPA3106D1. The number of circuits we expect to build is about

100 a year. We do not have access to wave solder facilities. Any idea how to solder this chip to the PCB?

Thanks, Edward.

Two techniques come to mind:

is a good link about using a toaster oven for soldering.

Here we use a hot plate, get it up to temperature (385 C for our boards), put flux where the part goes, and heat the PCB up, put on the part, and pull it off to cool.

For rework and such, we use a hot air pencil.

You can purchase a small pre-heat oven which uses infrared lamps. The few we bought has a few temperature profiles which work well for solding surface mount parts to the board for either lead free or leaded solder. We usually use a small solder paste dispenser to put the paste in the right places. Cost will be about $300 for solder paste dispenser and $500-$600 for the oven. I use an SRA model 103 paste dispenser and a model T962A Taian Puhui Technology CD. LTD oven. We teach students how to design and build surface mount boars with these tools.
