ultra low cost pick and place?

I like what you're doing. 20 years ago anyone, hobbyists and tiny garage-shop companies could create electronics devices just as sophisticated and cool as big corporations. Today, SMT has largely trashed the creativity (and competition) that existe

I assume you have a part number system. If so, you should kit the reel with less parts first from the same part number. If you don't use part number system, then you probably have components sorted by value and size, which should lead to the same pri

GEOMETRIC DIMENSIONING AND TOLERANCING (GDT) Using and applying GDT to printed circuitry and assemblies is very much like applying it to any other design for manufacturing (DFM) or design for assembly (DFA) requirement using concurrent engineering (C

There is a new toy I received today: a NeoDen TM-240A automatic desktop pick and place machine! I’ve kept my eyes on this baby for a quite a while, and finally decided to make a purchase last week. The shipping was very fast: DHL from China, a total

0201 and uBGA

On an assembly reflowed in air saw the same thing: 0201's with a grainular solder joint, but 0402's and above with perfectly formed joints. Reflow profile all within acceptable tolerances. Reflowing in nitrogen solves this problem, but increases t

Tg and reflow

Electronics Forum | Fri Dec 16 18:37:10 EST 2005 | mdemos1

Hi. I am trying to understand Tg and how it relates to reflow. With the higher temperatures of lead free, we have been looking toward laminates with a Tg of 180 instead of the current 140. My question is a little more general. In either lead free

Board Stacking and Conveying

Hi Gurus, Looking for alternatives to line makeup after reflow oven. Currently, I have a continuous on flat belt conveying out of my reflow oven straight to an EOL bench. The operator manually picks up the board off the belt (there is a roller at t

Reflow glue and past.

Electronics Forum | Tue Feb 08 12:36:28 EST 2000 | Charlie

I'm looking for information from both those who do cure glue and reflow past with the same profile and those who have tried and decided against it. What were the problem? What are the limitations?
