What is that garbage. How about you add flamer to like and dislike. I would have used it at least 3 times in this thread alone.

I forgot to add that we are using a 3 mil stencil. It seems like to me that may be there isn't enough flux left when we reach liquidous?? About half of the solder spheres do melt and wet on each pad, but the top half of each solder joint is just the

Hello, We're building some boards with 01005's and the only issue we are running into is the solder is not reflowing. It's the damnest thing, we are having no issues with the printing process or placing the components, the two areas we thought we wo

you are seeing a typical issue that is caused when such small volumes of paste are printed....there are several reasons for it..the tiny amount of flux in the small deposit becomes exhausted much quicker then it does in a larger deposit ( the flux ma

How can one go about defining the complexity of a PCB for characterizing reflow profiles A large balanced board may be easier to profile than smaller unbalanced board ? Any ideas how to define an index to calculate the complexity based on size,weig

Take a look at the product here: http://www.kicthermal.com/products/KIC-Auto-Focus.pdf KIC uses a previously profiled product library to calculate in spec reflow profiles for new products. Just enter you dimensions and if finds a solution for you.

Hi, Yes did use that. but how to claassify a board based on complexity still remains ? Davef made a begining will appreciate if we have more comments Thanks

Our old friend Bob Willis posted at his site [ http://www.bobwillis.co.uk ] a document that may be a good starting point. In the "Download" section, look for "New Product Design Evaluation Form (Word.doc file)". Certainly the number of solder connec

I don't mean to be rude, but what you are saying rings a bell as being questionable practice.

hi, I am sorry if i sound offended anybody. What i meant is that we are handling boards which are from major manufacturers like hp / compaq / dell / ibm / intel. So if annybody has experience of handling it..than they may have reflow profiles of sa
