Interesting stuff. I must admit that I am unfamiliar with that product but we use quite a bit of Dow and they are overall excellent silicone coatings. We do nothing but conformal coating here and bubbles are usually from curing to quickly. Without kn

Has anyone come across any good visuals for the solderability requirements for component leads with toe-down configuration? IPC-A-610 does not have any visual aids for this category and our inspectors are having a difficult time assessing based sole

Hello Can someone recommend a cost effective solder printer that does not require stencils. We are currently using a Speed Print 200 machine but this requires us to spend a lot of money on stencils and wait long lead times for these to be manufactur

The only thing I have ever heard of that prints solder paste (accurately) without a stencil is a Mydata MY500. You can buy thousands of stencils for what this machine cost. You should not have long lead times on stencils. We get ours next day for no

I use a program called Cad2Cad to convert the data for our Opals. It was given to me by the Assembleon sales rep when we were shopping machines. It was free at the time but I'm not sure if you have to be under contract to get it from them now. I take

The program reads the Altium PCB directly and does some preprocessing, like centreing DPAK's etc. The ordering of components can be sorted by Designator. Top, bottom, SMT only components can be selected. There are 2 variation on VIOS :- JH_YM100_VIOS

Hello, We developed a small software tool - PROCAM which imports Gerber data and allows the user to automatically convert pads to components and then outputs directly a VIOS file for use in Topaz or any other GemLine machine. If you need more inform

I hope to get some feedback here. I have a SMD connector that reflow-solders quite poorly (I guess solder paste or profile issue). On the X-ray I see strange bubbles, does it mean there are voids under pin? Generally I am not satisfied with the sol

Hello, I am having a problem with a large amount of solder balls surrounding mostly the legs of fine pitch ics. There seems to be a large collection in gap between the pad and the solder resist. They do not easily wash out. Our profile seems to be

OK. You used a thermometer to to check your recipe. How do know that the temperatures that you selected are correct? Your solder balls indicates that it's possible that the temperatures that you selected might not be correct. Without belaboring an
