Hello there: Could anyone help: 1- In a double wave wave solder M/C, is possible to completely eliminate the second wave without affecting the quality of the solder joints? 2-From a quality control prespective, what is the minimum accepted length of

As long as you have a continuous profile with required soak and dwell periods, the zone lengths do not matter. For lead free, usually ramp to peak is preffered.that is with minimum soak (you can not avoid soak anyway. You can achieve the profiles irr

We have HRFT-301U ( staple bend) is fairly easy to set up. All you need is t-handle Allen that I believe is provided with the machine. All adjustments to form a part, both pitch and lead length are mechanically adjusted by sliding the forming and c

JB, I have found the same thing with the visions codes & auto-teach. I'm sure there are some nifty tips/tricks to make all this work faster/better. I just wish they were documented in the manuals better. One thing I did on a yellow tant just a few d

Thanks for the replies. The single missed lead is a bit odd - we usually have an entire area missed and that's due to the board not sitting properly in the pallet fingers. I figured in this case it was likely due to poor fluxing? We have always str

Two things: 1 IPC pad calculator is an excellent resource for you and your board layout staff. Consider that working together with the calculator may allow you both an opportunity to balance your interests. 2 It's unlikely that the ceramic parts h

How are these connectors and dips oriented? If the leads are parallel as opposed to perpendicular to to the wave this can promote bridging depending on spacing and length. The long leads showing icicling are most likely either inadequate heat OR the

Alright Dave, I need your special search engine on this one. I am looking to see if there is any way to convert package dimension information ( length, width, lead count, etc..) into one of the following: 1.Gerber, 2.GENCAD, 3.IPC-D-356 I would like

IIRC the IPC spec for oven profiling says the thermocouple leads should not be more than one meter in length. I think when you can afford it, getting a data logger to go through the oven would be a good idea. But if you are going to use the very lon

I am not familiar with your flux but with no-cleans (which I use) the primary cause of icicling is the amount of flux solids left on the board prior to wave and how long the board is in the wave (2.5 to 3.5 seconds should be OK). The amount of flux s
