we have 4 bottom IR heaters and a 2 zone bottom Quartz heater (2 lamps/4 lamps) and 1 convection heater above zone 1 IR. we have very tight restrictions from customer and I could send profile view to your email if possible

Maxtim- I have used APE's Sniper, airvac, Mecal's 3500, PDR, Pace, and MArtin's rework stations. APE Sniper does the Job but to much automation and not user friendly software. PDR is to much IR and no convection. Metcal's work good now with the ne

We are using hot-plate. It is the safest method to rework aluminum substrate PCB's. http://www.martin-smt.de/en/rework/products/pre-heater-hotbeam.html "For efficient rework on heavy electrical systems with flat bottom surface and LED PCBs the pow

The shorts happen at corner of the BGA. The PCB thickness is 1.6mm, It is a PC motherboard with all thru hole connectors mounted on.The preheating is done using IR heater and the temp is 120-160 for about 70-80 sec.I am using ERSA IR550A

Would we be able to schedule a demo for this model? If so, would this have the IR top heater as well? In the event IR bottom heating does not work, are there models with alignment/placement assistance that we can just use with a conventional hotpla

24") The RD500V has three heaters and it uses a combination of hot gas and IR. The area heater can range from 3600 watts to 4800 watts with a bottom localized heater that is 1 000 watts which has adjustable z movement. The price of the RD500V series

hi, we have recently got a PS-400 BGA reflow from china. has hot air top heater, IR & hotair bottom heater and 6 IR bottom heaters. We are able to handle all type of desktop boards but in few of the laptop boards we still have problem. The profiles

I agree with all of you. If it is a good forced convection oven, the bottom side of the PCB will get very close to reflow temp and will probably reach reflow temp. Plus your oven may fight your settings. The lower heater temp settings will never b
