A little more information on your current wavesoldering process would be helpful in helping you. Information like what kind of flux your are using,how you are applying the flux,what preheat temps you are using,and your conveyor speed. Without knowing

Lozie We built our own soldering robot using pace soldering irons but we have considered a Apollo Seiko bot for a different facility. I'm curious to know what kind of life you get out of those Apollo Seiko irons with lead-free solder. How many solde

Russ makes a good point. While your profile probably meets your paste supplier recommendations, it may not be proper for the component. * Paste suppliers offer general recommendations for tin / lead interconnects. You need to modify that for board

Bill, Any reflow oven sales guy would be happy to help you with a snazzy sales pitch. I also had some info from paste manufacturers when I pitched it to my boss. Essentially, I believe, it comes down to control. You may be able to get a 4-zone ho

It is usually done differently. Sensor is in the solder. Once solder becomes goes below the sensor, it triggers you need to add. I believe it measures temperature rather than distance.

Istvan, The advise from both Roni and Mike sounds right on the money. The problem is most likely that your PCB is not completely dry (the flux has not completely evaporated) in the area where these solder balls occur. You have a number of differen

Where are the shorts occurring on the 96 pin connector? Are they consistently in the same areas? It looks as though there are a number of pins connected by traces on the board, and/or the ground plane. This would cause a lot of repeatable shorts i

Hi all, I am just wondering is there any other Lead Free Standard Profile for IR reflow besides the standard provided by Jedec ? What if the profile that i use is different from the one provided by jedec ? Lets say the peak temperature for Jedec is

If you know "soldering Pb free (Sac based soler) to Pb/Sn coated lands is a no-no," why would soldering with Pb/Sn to Pb-free coated lands be different? If you are going to do this, follow the advice of an earlier poster who recommended higher peak s

Robert: Several points: 1 Dross is a mixture of various things with no "fixed" composition: � The obvious things are metal oxides mixed with metal and this can vary in color with temperature and composition - remember some intermetallic oxides form
