Manjunath The top camera will be used for probably 90-95% of your inspection needs. However, without side cameras that 5-10% of uninspected parts can be a real pain to manually verify. What you need to figure out is what is your product to inspe

It turned out that only SF heads support "fine" mode, while FNC does not. Probably because above the FNC nozzle there is a "circle" rotating the nozzles, and in fine mode it can interfere with the reflection of the camera light - the element is lower

I have a single-view camera on a Topaz-X machine. When I define a connector type element - it displays messages like in attached files. If I change the type to IC - no problem. There is also no problem when "learning&quot

I suspect configuration too. From memory, only certain heads are assignable as 'Fine'. Changing this parameter in the component data to Standard or QFP will most likely cure this as any head will accept those two options

I'm trying to get a better understanding of the cooking process of pcb's. The use of nitrogen in reflow and wave ovens. Seems to have a wide margin of acceptance as a standard gas to prevent oxidation of metals in the board. Has any one heard or us

If people use an inert gas, they use nitrogen for mass soldering. Inert gases get progressively more expensive as you move down the periodic table. Many times no-clean flux is less active than other flux types. So, people use an inert gas to lower

my oven has a built in profiler, it works fairly well, but it can not predict changes. my main concern was about the time right before reflow. i know that's where the flux is activated and i was worried that i may be spending too much time at the tem

You can keep only the 5th zone as the reflow zone. And lower the first two zones to keep a good ramping rate. Meanwhile,please note the ting temperature in software or control panel is not the exact temperature in your PCB, you'd better get a KIC or

Take a look at this. Remember, these are only guidlines and can not replace any paste specs. As Real Chunks said, a profiler will be of HUGE help. We use this to determine what our top side temps are and to see if we have any problems with heat sen

I am trying to optimize my reflow profile. i have a 5 zone oven. lead-free: for the 1st 3 zones, i am good, at about 150-200 deg for 150 seconds. during the 4th zone, i am at a temp of 200-220 for 50 seconds. during the 5th zone, i am at 220-245 f
