Regarding nano coatings : Nano coatings are susceptible to wear during the printing process and cleaning processes. As they wear they flake off and can potentially contaminate your solder. There is not a lot of independent data available on this so k

We use a small surface mount connector that has two alignment pins to ensure proper alignment. It works fairly well. I'm thinking that this simple alignment solution might work well with lead less parts like a BGA or QFN. I can hand assemble QFNs

I'm with Dave on this one. In my opinion, it'd be much more cost effective to add an alignment legend. Speaking from experience, as I've hand placed many BGA's, all you really need to do is hit the pads. Even with Pb Free Chemistries, the part should

Pure Tin terminations can be mitigated for components with solder terminations less than .030" in height from the PCB, by using 6 mil stencil with Sn63/pb37 solder paste. That's the simple story for our customers that require it. Beyond that height w

Our company has recently changed the way our cage gives our SMT Department their parts to try to better control inventory. SMT now instead of recieving reels recieves strips with only 2-20 extra parts depending and the size/cost of the part. Does any

I'm guessing you're running small batches of boards on the MyDatas. We had the same issue with management when they decided to save on parts (not realizing it cost them more in time and more frustration for us). We had Agilis feeders so that helped.

Hi Stevo. It's been a long time since we've talked. I hope things are going well for you. I haven't talked to Daan in at least a year. His site has been in disrepair for at least that long. My last email addresses for him is d_terstegge'at'signaal'd

thomas31, We have been using Vi Technology 3k3 and 5k machines for about 5 years and have been very happy with them. They are easy to program, mechanically robust and have good support if you need it. If possible, you should narrow it down to

Hi Thomas, AOI Systems provides very affordable bench top and inline AOI systems for both pre and post reflow. Many customers are purchasing these units for pre-reflow inspection due to the ease of programming and access for pre-reflow adjustments. A

The Dima PnP machines look really nice -- exactly the size and capabilities we will need for the next 3-5 years. Apparently, however, they are supported in the US by Manncorp. I have nothing personally against Manncorp, but have heard bits here and
