0402 Placement with Fuji CP3

Electronics Forum | Wed Apr 28 17:41:44 EDT 2004 | longpham246

Hello! We placed quite a few of 0402 with our CP3 using 0.7mm nozzle with the same feeder as you had. Pick up can be adjust and calibrated, but that is not the problem, I agreed with you on that part. The trick is you have adjust and play around wi

Hi Jacky, It seems you have solder bead problem, beading occurs when the solder paste brick splatter as a component is placed into it, after reflow, the splatter becomes a spherical solder ball. Hope this will help. Steve USA STENCILS

Spanky, It sounds like you are looking for a recipe to use when you do get an assembly in that has 0201's on it. We have worked with our customers worldwide in the development of the process to use 0201's. Most equipment manufacturers out there

The Sanyo Short machine, with 80 8mm feeder slots is a great high speed with a small footprint. The new TIM-5000 flexible placer offers an incredible range of components and flexibility. You may want to consider this option also. Depending on your bu

I think the Universal and the Siemens machine are a good marriage. However, dealing with two different vendors may create additional difficulties. As both parties want to make the deal with you, you might want to bypass the sales people to get more i

Have You adjusted the placement properties of your pick n place machine/software for a 0402, I'm thinking x, y and add a little z. seems to work for me :) (as a temp/perm fix) thinking also about the numerous variables involved. Your printing process

Minimum Component Spacing with Minimum Solder Mask Width of 4mils

Desire to push the spacing limit as usual. If I place two 0402 components spaced 7mils between the edge of the two components adjacent pads, which allows for 4mils solder mask webbing between component pads, what would the risk be? Potential for sold

Hi there!!! Actually, all mentioned ideas were significantly related to the cause of tombstoning. But, based on what DL said, you have to check the placement of your 0402. Coz, based on experience, i evaluated the different variables for the root

All of the replies have merit. Here is another one. Because the cause of the tombstoning is wetting forces that are imbalanced, and one end wets faster or more readily than the other, the 0402 lifts up on that end easily because of its low mass. Incr
