Hello, yes you are absolutely correct. I agree with your point. Last week,I personally checked out my board on Heller 1088 which is a 8 zone reflow oven (4 on top and 4 on bottom) and the soldering came pretty nice. So comparing with that situation

Hello, I am looking for input on the 7 zone convectional reflow oven on the temperature profiling. I having a problem with the flux/solder spattering on the Au cotact fingers. I have ran some experiment with the soak time and reflow time. Anyway,

What do you mean by solder in ROHS. Can you please explain me little bit. Is that really important while doing lead free process. Also, please tell me wether a 8 zone (4 bottm and 4 top) reflow oven with 300 degree max.. Is good to do the lead free

Sumote, I suggest DESCO ESD safe het gloves, these gloves have a polyester exterior fabric with woven conductive fibers to ensure static protection. Inner lining constructed of material for use in heat assembly processes, can with stand 200�F maximum

Dear Sumote, I would suggest DESCO ESD safe heat gloves, we are using them at our facility, these gloves have a polyester exterior fabric with conductive fibers to ensure static protection. Inner lining constructed of material for use in heat of 200�

Takt time (without a google search) is the rate (amount of time per pc.) at which stuff gets made on an assembly line, a workcell, a hi-speed SMT line, CNC machine cell, etc.... Takt time is governed by the gate (the slowest person, machine, etc. in

The 300 degrees is the temperature as measured at the sensor. The actual air temperature just above your PCB may actually be much less. If the oven is properly calibrated then the 300 should represent air temperature at the board but I have seen ma

The longer the oven, the better. You will have much more capabilities in creating the precise profiles the way you want them(with10-12 zone oven). I have worked with ovens from 2 to 12 zones and the difference is huge. In my opinion try to get a 10zo

Sounds like your volumes are pretty low. Pick and Place is the bottleneck in the assembly line. Consider an oven that can keep up with the throughput of your P&P. "The best" is determined on individual cases for a specific application and enviro

I don't have one, but a lot of ovens of this vintage are on the market because they DO NOT cope well with lead free processes. There is one of these on eBay right now and it even says ROHS is right at the limit of what it can just about manage so thi
