No net or deflector in DIY nozzle, but have deflector in the end of the heat gun. The heat gun I used didn't have the correct type
of round deflector needed, so I had to make one. Because of my design, a net would ruin the flow of the hot air.

Another heat gun already having a round deflector would have been better than mine, but mine did the job ok, as you can see
from the burn test pictured earlier in this thread.

Who made the hot air gun part? Aoyue?

No, it's a very cheap heat gun you buy at any hardware store.

Many thanks for the reply Code.

I have an Atten 858D, which has the deflector, should be fine with that then ;)

Off to the shed to find parts then! I'll upscale to fit PS3 RSX.

Regards,

Rik

Its very interesting to see someone use such ingenuity to create a reflow machine from scratch. I was just wondering how much time and effort and then also money it would cost to make the whole setup. I guess if you had all the parts already maybe the cost isn't so bad but if you needed to buy all the components how much would this cost? Bottom heater, heat gun, lift for heat gun, TC with meter to read it and making the nozzle. Just seems like new cheap reflow machine would be close to same cost and better overall performance because of the controller ability to run a ramped up profile.

I'm not slamming Code for his project which is very impressive, just wondering about the cost factor. Also glad to see this post come alive from over a year ago... 8-)

Didn't keep track of the cost of this project. More time involved than cost. Certain it was below $200 US though. Controller was $85 by itself. I made this
in a small controller housing with the though in mind of using same controller housing for multiple tools. Like additional HR head made with hair drier, hot
plate, etc. The controller is the same Altec PC410 used in %90 of the machines out there for top heater, so it has the exact same ability to control ramp with
multiple-step profiles. If you are doing this for a business, you don't have the down time to build something to use for business use. You need a machine already
made to use, then maybe tinker on the side with DIY.

Does using a thermocouple with hot air to monitor MB topside temp (next to chip) require the thermocouple bead to be completely covered?

Searched high and low and cant seem to find a straight answer on this.

You don't cover the bead. I put a drop of flux on the pcb, then place the TC bead on that. If you cover the bead with foil tape or
kapton you will prevent hot air from heating that area of the pcb.

With hot air your TC will be giving you a reading of the hot air coming down from the nozzle, and not the actual temp of the chip
or pcb. With IR top you will get closer to an actual pcb temp because the pcb will absorb radiation, then give off heat to the
TC. If you watch videos or read posts about lift temps with IR users, they will have a temp of anywhere from 217C to 221C when
they lift temp. With HR, the temp can be 235C for 30 seconds before the chip lifts. HR takes longer to pentrate, but is more forgiving
thought too as far as popcorning chips.

You can use a very fine wire TC you can slide under the bga.
Will have lesser outside influence and give more accurate value of temp under bga.

Just get very fine TC wire, twist the end together and slide it under the bga.
A bead might be to thick to fit between pcb and bga.
You can also buy welded ones without a bead but not sure in the very fine wire versions.
