thank you for the reply.....this reinforces the same info about SAC305 that i had reviewed in other papers. Since this is an inherent property of SAC305, i am assuming 1. Wave parameter (temp/time) tweaking will not mitigate this? 2. what is differ

Tribol 1430 is the latest generation oil, 930 can't take lead free temps. Please see the following link.... http://www.castrol.com/castrol/productdetailmin.do?categoryId=82958955&contentId=6004371 If your getting alot smoke and residue, reduce the

Hi, I spoke to Kic about this at the Apex show in Feb. They told me it was OK to use the Orange Monkey Fur box for lead free. I even asked about my old side kic and they said it was OK also. I guess it depends on how high your temps are. I agree

Are you using lead free paste also? Are all the other parts on side 1 ROHOS ? etc.. can they handle your leadfree profile. Those need answered 1st. But to answer your question. Yes you can run the BGA side 1st ( hopefully with leadfree paste and ho

We use a no-clean lead free paste with our manufacturing floor temp 70-75F and humidity 20%-30%. We have found that if the time from pasting a board until it goes into our reflow oven is less than 4 hours we have no problems. If it is greater than

I have encountered poorly designed BGA packages that cannot be removed or replaced with BGA rework tools. I discussed this with the package designer. He recommended reflowing the entire board. I was finally able to remove the part by preheating the

The oven's maximum rating isn't really a good indicator as to whether or not it's good for LF. The real question is can the oven get your board up to the liquidous temperature of the lead free solder that you're using. So, an oven that has a max te

Hi all, I need some one to give me a ballpark figure on yearly energy consumption of a reflow oven and a pick & place machine. I know it will vary greatly depending on various factors, but I just need some realistic figures. Say for a two shift oper

We have performed some EDS analysis and found high percent (approx 18% ) of Ni on surface of gold pad. Found Tungsten as well. This is an HTCC alumina package. Thickness of gold was confirmed and found to be in spec. We believe we are dealing wi

Has anyone else had failures with Leds from EOI? The part number is EOZ-ZARNCD0-DG. We are using a lead free no clean process using SAC305 solder. These are thru hole parts and our max temp is 244 for 3 seconds. Please if anyone else had issues
