Thank you Dave, that is almost the asnswers we use to give to our Customers when auditing they ask for component shelf life. But as you can imagine, they whant to see a quick information right on the label (on Reels, on trays, etc) like: Use b

Hi all We recently have a problem with component in package 0805 (capasitor 100nF). I have noticed that after reflow soldering only one lead of the component is soldered. The second one is just laying on the PCB land. We use screen printing process

Hi, Using good profiling makes all the difference. Its not easy, and thats where good software helps make it easy. If it's easy, then you tend to do it often, so things stay good. I like using this KIC software so much I wanted to take the profiler

We r using QFPs of 0.5mm pitch and r not getting any soldering prob at the end.But some new customer insists upon the thickness check of the solder paste after printing. At present we don't hv thickness checking system.We r controlling the amount of

Glad to hear a little success from ya Duckmann! i have stenciled mask in the past and I can tell you that stencils are expensive. They are basically a step stencil, you will need full thickness for the area(s) you are going to apply mask and you wi

A couple of things.. 1) The problem is more than likely on the magazine board itself (TC2), most likely the pal chip that stores the serial number and feeder information (you could swap this with a working magazine to verify) 2) The magazine connecto

We don't have experience on this, but first we'd talk to a technical type at our solder paste supplier. Baring that, we'd: * Soak a paper towel in a 'solvent' [ie Kyzen XJN, EnviroSense Enviro Gold, Petroferm Hydrex, etc]. * Place the towel in conta

Hi, Even if you don't use vision or a HYDRA head, the MYDATA should still sense no component, and try 3 times by default. Also, if the MYDATA does not place the component it will not be marked as places, so the placement program won't ever finish. Y

We are looking for some feedback on this situation. Please let us know if you have any ideas. Thanks in advance. I have been doing some studies on defects and such with our PCB's in prep for lead free and I've come to a conclusion about our process.

Comments are: * J-STD-001 and A-610 committees have eliminated the requirement that solder joints be "bright and shiny". Certain metallizations (such as gold) can influence the solder joint surface texture, but have no impact of reliability. Reliance
