Adam Generally the answer is yes. But there are many considerations. First a couple of questions 1 what flux are you using 2 Do you have top side pre heat in your wave solder machine 3 what is your measured top side temp. 4 what is your dwell time

My snmall company out-sources all of it's SMT assemblies. We do through work and have dome rework experience with SMT. All of our assemblies are built to "IPC610 Class II". We currently have no one trained to inspect to this standard. What is a pract

Hello there, Most probably, since the solder balls are entrapped, it is a process indicator, but refer to IPC 610-6.5.3.1 on Excess solder / solder balls / splashes - it really depends on what class you are manufacturing, and the minimum electrical c

Hi Ajay, Does your company currently use any quality standards or is it made up as one goes by the QA department? You might find that using IPC 610A Acceptability of Electronic Assemblies very usefull. This manual is our base line for acceptable or

For visual inspection table 1-2 seems to be in order here. If you can not see the bottom using 1.8 and table 1-2, it clearly would be a defect and rework would be the only option Well, my thoughts anyway, wonder if someone has other thoughts on thi

Hello, Heres my take. If the ends that are touching are connected by trace, and IPC-610 is satisfied, and the connection does not make a Parallel circuit where a series circuit is required, then I would treat it as a process indicator. That is, unle

IPC 610 says acceptable Class 1 (Class 2, 3 indicator) if they are entrapped/encpsulated balls within 0.13mm of lands or pads. or exceed 0.13mm in diameter. Defect Class 1,2,3: Solder ball violates min electrical clearance. Solder balls not entrap

You need to get yourself a copy of IPC 610. this has all the specs regrding placement and registration. chip aprts are allowed to have 50% side overhang. the fillet requirements are "evidence of wetted fillet" . I would not know if a cap being 51

Joris, Yep, very common to have those small blow holes in lead-free alloys. We used to get them very consistently on white-tin finished boards, and less frequently with gold finished boards, for what ever that is worth. IPC-610 actually allows t
