Hi, All seem good answers and food for thought. Additions you probably know. Flux Supplier Application Notes/Data Sheet. Many of them have run experiments to tell you what works for their flux on various machines. They might even give you optio

I am glad this thread is still alive as I have a concern. I have just entered the wave soldering business after many years in smt. After wave I am getting icicles or flags on my component leeds. My temps seem to be all with in spec as does my NC flux

A lot of component vendors already shifted to Pb-free products but our process is still using 63Sn/37Pb solder paste and SMDs. What would be the result if we introduce some Pb-free components to our current process (i.e without changing the reflow p

Hi, The normal electronic components you purchase should have lead free variants. Also, all solder paste manufacturers have lead free solder pastes, so you just need to get the paste specification, and then re-profile your oven for it. Temps are hig

Hi, Does anyone have any experience of using electrically conductive adhesives, including info on the following? 1) Autodispensing/screen printing 2) Curing temps/profiles 3) Quality/conductivity of joint 4) Product recommendations Our customer w

I'm inclined to believe along with others that if you don't smell it, and the flow rate is consistent (hence, your profiles aren't suffering from fluctuations in temperature due to fluctuations in circulation) you're probably OK. It does beg the que

Does anyone have any experience running Aluminum Electrolytic Caps with a SAC305 alloy. The profile for the solder calls out a peak temp of 235-255C and 60-75 seconds above 217C. Most can cap manufacturers are calling out for 230-245c max for no lo

Does anyone have a list of SMT components with their weights? For instance, a PLCC64 pin = X grams. I am not even sure if such information is really valid but it would be interesting to know when developing a reflow profile for convection ovens on a

Hi, sounds unusual if your profile is accurate that you have so many residues. Had a similar problem before with no clean flux and with various flux manufacturers, and all residues were down to excess flux. This does not help your case though. How a

90% of the battle with thermal profiling is your thermocouple attachment. That is Process Engineering 101. It's just like painting your house. The masking and prep work will make or break the end result. KIC did a DoE on which thermocouple attach
