I remember Metro Nozzles mentioning that they are bringing out a new "blade" nozzle soon to allow closer density placement of 0402's & 0603's than the 08MPF allows. Also noticed that you get far better placement with a 1 mil camera than a 4 mil, coz

Hi Colin, Are you using the 1206 package with 4 elements or one of the higher density smaller packages? With the first type you can get them in both Convex or Concave terminations, with most of the solderability problems associated with using the C

We ran an MVT 1820 Supra against a VT-Win-II for around 40K high density boards. One machine was 1/3 of the price of the other, more accurate in production, faster, and could handle larger boards. Guess which won? Fortunately we were able to loo

Hello, We had serval times problems with wavesoldering medium and low density boards. After analysis one time the problems where in the carrier an other time the flux was Not visible contaminated, ...etc. I wonder, does any one know a complete wav

the only problem i see here is the neighboring components (depending upon the component density) will surely undergo a second reflow during the rework stage for the BGA. this way the only lead you will have in the BGA assembly is if you are using HA

Check the temp of your pot. It may be getting cooler if you can notice a difference in pump height and density. You may have lost a heater element or two. You can adjust your pot chemestry, but why would you want to if your solder sample came back

I have checked pot temperature in different parts of solder pot and it looks like it is correct (250C). I have also lowered solder pot temperature and removed copper from the surface of the solder pot (operation repeated couple times). There is still

Just what is delaminationg during testing? Water washing should be sufficient to clean WS609. On the other hand, it's possible you're conveyor speed is too high to do a good job cleaning the high density areas. What kind of testing have you done to

8.4 * SAC305 => 7.36 * Sn-3.5Ag => 7.5 * '....in' [96.2Sn-2.5Ag-0.8Cu-0.5Sb] => 7.39 * Sn-4Ag-0.5Cu => 7.39, 7.44 * Sn-3.8Ag-0.7Cu (Multicore solder) => 7.5

Why yes, I regognize all the best. WML, I have an idea... I am going to call it, the Dunker. Instead of anyone foaming, I will get the wave operators to throw the boards into a rubbermaid tub full of flux/gasoline mixture and send through to the wav
