hot air solder gun

Do the epoxy of the smd chip with the chip upside down on double stick tape so it will be steady then apply the epoxy to the bottom of the chip use a jig to get the board placement right, then gravity should flow the epoxy through the pins and downward away from the board soldier pads.

Very nice work! I like the epoxy isolation. I like the way you put out the interpretation of the phenomena at the beginning. I do think along those lines too. Very very interresting!

I used to bench work with heat gun to correct misplaced chips, the heat gun is what you need to solder that with... little pricey but makes flawless solders , maybe find one used for 300$

Best Tesla info yet. Great work. The jigsaw starts to be put together. Putting dielectric first is our starting point. We have been too focused on the magnetic. It can be compared to saying a magnet only has a North pole only. ... Regards.. DC

cool, just ordered v1.1 pcb. gonna have a tiny RED soic\dip8 beefy board weeee!

Somebody please tell me how to build transcranial magnetic stimulation

Solder both sides first but with paper underneith smd . Remove paper and surround smd with blue tac. Drip some epoxy in and maybe even cover the whole smd for even higher voltage insulation .

Solder first, then epoxy insulation.

Make it easy on yourself. Flux a bare board. Tin the IC pads with small even solder bumps. reflux board and IC. Hold IC in place with tweezers on pads and tack down IC with a clean tipped iron. Clean board with flux remover. Cheap, quick, easy!

Genius idea, actually. Valiant effort!

Hai Ivo, misschien kun je eerst de puntjes vertinnen voordat je de ic erop plaatst daarna kun je het met je bout de pootjes een voor een vast solderen en heb je de hoeveelheid onder controle . Respect voor wat je allemaal doet super Ivo👍

Hi Ivo, if the voltage becomes to high and arcs over can an gate driver transformer be used instead or does it have limitations. I know you mentioned optocouplers so i thought maybe other alternatives might be viable .

Yeah, first introduction to SMT is initially intimidating yet with practice, it becomes as natural as Though-Hole (with the proper tools and patience). After a while, you’ll discover to ‘tack’ solder one leg and the opposing leg once the package is centered on the pads, firming it for soldering the other legs. A good quality liquid flux makes all solder flow for a pro solder-flow finish. Also, a ‘chisel-blade’ tip is the most universal for SMT as it has a fine point for tiny to a side-edge for larger solder area coverage ranges in one tip. Acetone is a good flux remover, as in Fingernail Polish Remover, inexpensive and usually easy to find. By-The-Way: Excellent work with the SMT daughter-board design.

Hi Ivo, I need your advice on IGB drivers. There are full bridge and half bridge drivers out in the market; which one is good to use. Thank you in advance.

I don't expect an exact answer but I don't even have an "in the ballpark" estimate. In your research the "Dead time" is critical. Let's say I was generating 2x pwm signals and wanted to capitalize on the big spikes. What kind of phase offset helps facilitate this? If 1% dead time is required for a 500khz signal. Period of 500khz = 1/500 khz = 2e-6 S= 2uS 2uS/100 = 20nS Would the phase offset in time for a 1% dead time of 2 500Khz signals driving the have bridge then be 20nS? 1% dead time will obviously be different for different resonant operating frequencies and I'm wondering if my thinking is ok. I guess I'm confused about the switching time requirements and concerned with latency iff (logical if and ONLY if) I need to generate 2 phase offset signals AND ALSO time a 3rd time and latency sensitive on/off. Otherwise I'm probably self sabotaging by overthinking.

Master Ivo i ear in your english speak nederland taal 😃

Have you tried using Avramenko's Plug instead? After mentioning your work to someone who's working in a similar space with resonance, they mentioned how they're using Avramenko's Plug instead with great success.

What is ether?

thanks! well, Ivo designs waay better important stuff, but i can def epoxy waaaay better, at present hehe **pats own back**

Maybe one drop of super glue would make it easy. So no glue gets on the pads 🙈

if you are interested in a small investor as your research progress please keep me in mind.

The temperature of the solder is too low
