our biggest problems with these parts is them laying on their sides after placement with a certain machine that we have. make sure that you do not have a planarity issue as well menaing that the leads are indeed below the body of the component. I a

If the problem appears to be random... we had a similar problem. We found that the belt which feeds the PCB through the reflow oven would jump or lurch ahead. It was barley noticeable but if you have identified the frequency and time of the compone

I had the lurching issue...turned out I needed to readjust to cog wheels on the exit side of the oven. The cogs had slipped, and the chain was actually getting caught in the teeth...to the point that as the wheel turned, the chain would stay in it i

The parts libraries are not readable text. The Sanyo software we used (UCT, I believe) would optimize the program for you. NCZ format is different than the 4785 .800 format, but if you can understand the 4785 format you won't have any problems

Thanks vickt. I'll shoot them an email. I haven't had any luck ripping apart the central library file formats in the binary format. Hopefully the HSP techs can help me out. I was also told you can export components created on the machine, to the fl

When running some double sided reflow boards through the Heller oven, some of the caps/ res's are falling off the bottom side of the board. I understand if the parts are too heavy they wont stay in the molten solder, but these particular parts are no

Your lighting would have to be pretty bad for it to be an issue. My gut instinct tells me you have bigger systemic issues. Operators will either be your best friend or your worst enemy. What percentage of boards have contamination? You might have t

Might want to check to see if the weight of your part has increased. If it has increased, you may not have enough surface tension to hold the part on the board. I am assuming you already checked that the component isn't getting hit by something in

Would I be correct in assuming that the solder used to attach the BGA ball to the device body should have a higher liquidous point that the solder used to attach the device to the board. If the peak reflow temp for SnPb is around 225 deg should the b

The solder used to attach the BGA ball to the BGA interposer would have a liquidous point dependent on the type of solder used by the device fabricator. If this is a lead free device [altho we don't think so], the solder used by the fabricator would
