I also have a comment about the preheat. It is usually dependent on the type of flux used in the solder paste. But all my experience with it was that the preheat is needed to ACTIVATE the flux, not

After looking at your profile, i cave a comment or two. Preheat to 100°C is a good idea to drive off the volatiles in the paste. This will lessen the possibility of boiling flux causing the part to

You can also use a skillet (or hot plate) for reflow work: https://www.sparkfun.com/tutorials/59#Hot%20Plate%20Reflowing https://www.instructables.com/id/Simple-Skillet-Surface-mount-Soldering/ At

Using the subject of your message post in Google, I found this DIY project: https://www.instructables.com/id/Hack-a-Toaster-Oven-for-Reflow-Soldering/ It appears to be a pretty complete project,

Hi Jim, I recommend you try electronics 101 group. Same server, same moderator, mostly the same guys, but more knowledge there. For your oven, I could recommend any electric oven modified to be

A recommended soldering profile can be found in the data sheet for NXP parts, for example, the NXP PCA9634. The QFFN64 chip will be the problem (or would be for me), and I avoid such packages

Hello Jim ^^) Have a look at the Elektor magazine back issues, they had published plans and all needed to make its own reflow oven for 'cheap'. and a pretty excellent one btw using an off-the-shelf

Hi there, Silicon chip Magazine have a electronic project on exactly this, they supply the pcb you fit the parts. from memory the pcb is about $15.00 AU , has a few smd parts as well as the

I looked through the messages for this group for the last couple years but do not see any discussion about DIY Toaster reflow ovens.? I know it used to be an easy thing to find on the web but I have

Wow Matt! My little experiment pales by comparison!? That is some serious work.? To be honest, I mostly did mine to see if it would work.? No drilling, just a couple of single layer surface mount

This is really exciting to see! I documented my approach to a similar technique some years ago, and would love to compare notes: https://reprap.org/wiki/PCBScriber

Some elasticity from a drop of RTV silicone behind the scribe in the nozzle, but it _does_ require accurate bed leveling.? I actually dulled the scribe point with a diamond hone down to about 0.003"

Is that spring loaded, or do you just rely on the flatness of the PCB and accuracy of the 3D printer? I noticed the lines look slightly wobbly. How securely is the scribe held in there? Press fit?
