I've used below: WEIGTH OF COMPONENT IN GRAMS ---------------------------- TOTAL PAD MATING AREA IN SQUARE INCHES GRAMS PER SQUARE INCH MUST BE EQUAL/GREATER THAN 30 FOR SECONDARY MOUNTING.

Placement of 32 pin QFN w/t ground pad

Electronics Forum | Thu Oct 15 11:04:28 EDT 2009 | spitkis2

Thanks Jim. Pressing the QFN into paste was what I thought of, just wasn't sure if it would cause solder paste to be pressed outside the pad area and possibly bridge with an adjacent pad. Do you recall the ratio of paste coverage to the pad area?

double side soldering

Like most things in electronic assembly, this is not astrophysics. People have pasted boards, placed components, turned the board up-side down, run the board through a reflow oven, and generalized about which components: * Fall off the board. * Don

Double sided weight of component to total pad mating area ratio: 30 gm per sq inch (50 mgm per mm2) Go to the sites of these consultant-people for additional background [I'm not sure exactly where on these sites to look, but both are laden with goo

Double-sided reflow with a Altera 240-pin RQFP

Electronics Forum | Mon Jun 30 16:35:13 EDT 2003 | davef

Hi Steve We don�t double reflow this part. We wouldn�t consider it without a fixture or some other support. You know that sound, the almost involuntary sound that patrons in a restaurant make when a waiter drops a glass or a tray? It�s kind of an

Double Reflow (Weight/Surface Area) Ratio Rule

Electronics Forum | Sat Mar 21 12:19:51 EST 1998 | David Pick

I have read somewhere of a ratio of component weight vs. surace contact area rule for double reflow soldering. This ratio is the maximum weight vs. surface tension to hold a component on during the second reflow. With this number, a person could weig
