assembly issue on metal core

[Jessie Barry]

we have little assembly issue due to the metal core and solder melting issue.
You have any idea what is the best way to assemble metal core boards?

[Eva Liu]

I also face the same problem, any one can help?

You will in most cases have to use a special temperature profile when reflow soldering them since the metal inside them takes a long time to heat up.

As for hand soldering its best to get a board preheater. Its a device that you set your board on top that then uses heaters or hot air to heat the board from the bottom side. Keeping the whole board at like 100°C helps hand soldering a lot since the core wont take away heat as quickly.
