you can reference JESD97 for labeling LF components, also. i have sent a similar letter to our suppliers and am fielding questions ranging from, what is a MBB to why such strict packaging requirements. i was surprised to know that the requirements

Lou, You should look at the ERSA/Modus AOI System! The Modus AOI uses a high resolution industrial scanner rather than a camera mounted to a gantry. It's way faster (12 seconds for whole board ) and can do everything that a camera can do and more

Lou, There's nothing like working with it yourself. We went through this exercise several months ago. We evaluated MIRTec, YESTech, and MVP. We were looking at benchtop units, so all 3 companies were willing to send in a "demo" unit for 3 weeks.

Dear All, I have 1 product that using solder bar from vendor called Asahi. After wave process, we found quite a sticky flux residue remain on the board. Eventually, have huge impact on our ICT fisrt pass yield(FPY). Current FPY is a the range of

1. If I go to the Pb-free solder paste, is it necessary that I have to change my reflow oven OR just by changing with respect to solder paste specification, I can reach my goal? 2. What is the �Low- Temperature Phase� in any solder paste alloy? 3.W

Good Morning Everyone, I just wanted to get a feel for what other Contract Mnufacturers are doing. Do you allow a production PCB assembly with glued SMT components to be wave processed more than once? (e.g. the first pass did not produce acceptable

Hmmm.... I had Intel survey my process on a mixed alloy line for 2 days. They periodically removed boards from all stations on the line (including post reflow). Boards were "crushed" and spearated into constituent plastic, ceramic and metals. All

What software level do you currently have on your machines? If you have UPS+ 6.2.x there is a huge improvement. In the SOIC/QFP or any leaded catagory you will find a check box under the vision tab called noise filter. Check this box and the software

Mika, I think you will find all board houses "clean up" their customer's files to suit their shop. Depending on the severity of the change; I think they take the attitude that they will not inform you to avoid an argument going backwards and forwards

There are several alloys had been using in the industry. For SMT: most people use SAC305 For Wave: most of them use SAC305,SC100C,SCS7,and SACX0307. Of course, different alloy composition have its own recommended profile. There is no such rule tellin
