What temperatures did you read on the QFP component leads during reflow soldering?

Have you looked into Sipad? They will pre-paste your BGA and other component areas with solderpaste that has an adhesive on it. You can then hand place your components and run through a reflow. Here's their site: http://www.sipad.com/

I'd be more concerned with the pcb itself then I would be with standard SMT components. Are you using a PCB with a high Tg? (170 degrees C or greater)

I look more for a software to handle our data. I know partminer.com from the past, it's more like a search engine as I remember. Great for substandard and fake components if I remember too.

isd.jww: First, the original poster is talking about pads, not component leads. Second, you're correct that chrome plated component leads can be attached by spot welding or crimping a solderable tab to the lead and then soldering the tab to the boa

That's how it's supposed to work, but is working correctly on the components that are loosing heat sinks for you? We have two choices: * Poor solderability of either the component or the heat sink ... OR * Wrong solder preform material

hi, lately I have problem with smd leds.After reflow 2-4% of leds are broken.I think , that reason is bad storage of components, because in our stock the tape with leds have not Moisture Barrier Bags.My question is ,how you storage components, which

Do you guys have a reference document that lists the number of components per inch / foot etc for all the various sizes - 0402, 0603 etc? I am in need for a project we are working on. Thanks
