Is it just me, or does anybody else have problems with open connections on small surface mount headers and connectors? I am talking about small 20 to 40 pin devices, 25 to 50 mil pitch. We put these things on the board, the feet look like they are

Hi SMT Engr With a double-header connector do you mean Double Level Right Angled Header Connector. If so there is a big difference in heat sinking capacity between the two rows, as where the pins of the top connector absorbes twice as much heat as t

Typically - hand soldering as you are currently doing. Should your volume justify it you can invest in a selective soldering solution, these might take the form of a robotic arm that essentially replicates manual soldering or a solder jet similar to

Why not do the other side first. And paste the pins from the connector side? Or maybe using solder preforms on the leads might work if you are afraid of the connector squishing the paste. I'm guessing the headers are raising because of the outgassing

Just what the subject says. If you are what type of machine are you using, is it mechanical or vision centered? What is the reject rate? Thanks for any help. James

When the pads on the board are too large, the component tends to swim. This skewing can be a BIG problem with connectors, eh?

Dear Frank, could it be that your component legs are coated with a leadfree finish? This can have an inpact on soldering when your temp.peak in only 220�C and the melting point of pure Tin is 237�C. Best regards, Daniel

did you try using double header connector pin of a different lot? Indy

Sr tech, It is in the PCB header information. F2 from the layout editor then F1 to view through the camera. Regards Chris
