| I've never seen this before. Today, I got this tombstoning on Tantalum Capacitors (Okay, I saw that before) | Here's the part that seems weird to me: | -They didn't tombstone onto a termination - they went onto their sides! That's right, both ter

Gregory, I think that the profile is too radical, i.e. zone 6 to zone 7 temperatures are too far apart. I would guess that the solderjoints have not all reached 183C in zone 6 which is why the uBGA's do not have a symmetrical ball collapse. You may

Hi Jeff, Sean is correct. Although ultrasonic technology will work in post-reflow de-fluxing applications, you will receive concerns regarding ultrasonic �damage� to wire bonded components. Much has been written to combat this belief but the conce

Most of the machine suppliers Fuji, Siemens, Universal and Panasonic did regret that they were building glue machines. Applying adhesive compared to placing a component looks so simple, but it is not and the defect rate is higher than placing 1206 c

Oooo, thanks for the conversion. Being metrically challenged, az a skratchin ma haid thar fer a mite. We do a G-10 160 thou and have similar issues. Now, we�ve talked about barrel fill [ie, slowing belt speed, increasing pre-heat temps, etc] befor

When you look at the capabilities of Combo machines they tend to sacrifice performance when compared to separate X-ray and AOI machines, meaning they don't do either the X-ray or AOI operations as well as a machine that was designed to do only one. A

First, I don't have a clear fix on the problem. Please drill-down to more detail. We appreciate that you probably don't know the parlance. Just describe what you have and then what you'd like to have. Second, most 0402 LED are fabricated just lik

Grant, No-Clean paste + IPA = White Residue! #1: Stop using IPA #2: Switch to either a solvent-based de-fluxing chemical or an aqueous-based de-fluxing chemical. If you are using an ultrasonic cleaner for your boards as stated, do not use sapon
