Mikeal�s approach is one of the more cautious ones. IPC/JEDEC J-STD-033 clause 8.6 talks about 200�C body-temperature not to be exceeded and how it�s best measured. If you go for that method and you made sure that in your wavesoldering (that�s what

For double-side reflow boards, take note that if you have moisture-sensitive components on the first side, you will need to track their remaining floor life up to the final reflow. This is because the reflow process is too fast to effectively remove

The other important issue relates to moisture sensitive devices (MSD). If you have MSDs on the first side, you need to track the remaining floor life of the components on the partially assembled boards between the first and second reflow. Contrary to

hi, I am a research student in Electronics manufacturing at RIT. We are planning to assemble boards using lead free solder paste. I was wondering would there be any changes in printing in using lead-free paste"Sn-3.9Ag-0.5Cu". Thedensity of Sn-37Pb

Hi Guys, I have a customer who requires 95 paper 8*4 CP6 feeders on the setup. We dont have the required quantity but we do have embossed feeders that we could use. Just looking for some onfo. on performance using paper in embossed feeders as I migh

Dear Vicki, If you decide to use high temp paste, I suggest that you verify the rating of the components, especially for moisture-sensitive devices which are normally qualified at peak reflow temperatures of 220-235C. The specified floor life will

Hi Steve, It sounds like your product will have many moisture-sensitive devices on both sides. You should be aware of the additional controls that are required to insure the reliability of these components in a double-side reflow application. The

Thanks for your input. I heard about the component size from someone else as well. They said if the component is greater than 8.4mm, it will not load another component next to it on an adjacent head, which is only 16mm away. The PLCC6 LED's are 5

Peterson: Ionic flux residues when combined with moisture and a voltage differential can plate conductive �fingers� on the surface of a PCB, but that doesn�t sound like what�s going on here. Your NC flux should not be particularly conductive. For
