We are running a selective solder machine using SN100C alloy. We have had J-STD-001 analysis performed every 2 months and our last analysis showed our nickel content at 0.104%. The max allowed is 0.100%. We changed out the pot (only 30 lbs) but I'

Does anyone know of fully automatic pick and place machines that can pick up parts either from small pieces of cut tape (i.e. 0402's, 0603's, SOT's) or components loosely arranged on a tray (not ic's that are in matrix trays)? Application is proto

You can use cut tape on Mydata machines fairly easily. We are a high mix, low volume manufacturer who has to use cut tape often as that is what our EMS customers provide. It is does take more time to load/unload than a reel does so you need to fi

I have been working on Pb-free assemblies of screw terminals (terminal blocks). Unlike, other pin-in-paste conducive components, these component has square headed leads. We have been facing issues with the solder dripping into the oven. We were able

We know nothing about your: * Solder alloy * Materials of your board * Materials of your teminal block * Process setup of your wave * Wetting condition of the board or the terminal block ... but we'll take a guess anyhow. Tin-copper based solder all

We replaced the tactile sensor's linear actuator on a MPM Ultraprint 2000 HiE. Now we are getting a Tactile Hardware limit error every time we try to find the stencil height. I was hoping some one could explain why we're getting this error and any i

Here's a few ideas: If it has one, make sure the flexible coupler set screws are tight. Replace the tactile switch (often these appear to work fine in I/O but do not work properly in production). Clean and oil the tactile plunger if it has one. M

Thanks for the suggestions! It ended up being that a wire on the amplifier card in the lower drawer came loose and was making intermittent contact. Tightened all the wires down and the problem has gone away. Now we have a new problem. We had to repla

Hi, This may be a bit off the subject but thought I'd ask just in case. I am looking to identify a process / equipment for attaching solder balls to flip chips. Solder balls are 75 microns in diameter. With BGA's there are reballing kits that use
