Dear All I have a question for the reflow machine. I'm using Vitronics(Mr933+)reflow. The peak temperature of the (Chip, LED, SOT) component higher than (QFP,LGA) about 4 degree when i measured proflie. All of them on the same board . I don't know w

In short physics. A large Black object will absorb more energy than a smaller non-black object. Thus the temperature will remain lower around the black object as it heats up ! sarason

Different points on the board couple have different thermal masses. Look here: http://www.ecd.com/portals/5/products/vmole/V-MOLE-Verify-3-Thermocouple.pdf

In general, smaller objects heat up faster than larger objects because they are lower mass. For example if you heat up one liter of water in pan and two liters of water in another pan with the same heat energy applied, the smaller mass will heat up f

The lowest peak temp. I've had the pleasure of working with is 240°C +/- 5°C. I can't imagine a manufacturer going much below that and still saying it's lead-free compatible. It would be interesting to know just how much TAL plays into the affect

Hi, There is one thing missing still, you must put a TC from the bottom side of the BGA by making a hold on the test board at the TC can measure the temperature at exactly the middle of the BGA. You should be able to the dual time and peak temperatu

Peak Temperature during Leadfree reflow

Hi, AJ, In general, the peak PCB temperature is variable depending on the profile used. We try to keep our peak temperatures in line with the paste manufacturers recommended temperatures; ignoring the peak temps for the PCBs. For the peak temps yo

Lead free component on leaded process

Could you advise what is the min and max peak temperature for this process. Presently, my leaded peak temperature at the range of 215 - 225 deg.C And how do I know that the solderability is at optimal. Appreciate your help......
