Depends on the product & constraints your having to deal with. I've used the following in the past; Stepped Stencil, Overprint, Additional dispensing equipment after the print process & Solder pre forms

Thanks for your replies guys, there's some good info there. Dave, answers to your questions: The stencil was initially a big problem as with the Egineering Model's (EM's) and Engineering Qualifing model (EQM's) we kept getting short circuits due to

1. Verify all the part had load to machine. Get ready for the profile. 2. Run the board with double side tape. Is better to run one board for each machine. 3. Verify all the placement ( missing, misalgnment,etc )and check the value using meter for a

You can certainly venture out to the nearest lab for in-depth analyses. But since you mention 2-3% defectives in a batch, there is much you can do in-house as well. Measure the height of your solder paste deposit (in zero print gap condition)across a

Hi, I am looking for a Solder jet supplier. Micronic does not support my small dot size LEADED solder paste. I can not use stencil print because my substrate is fragile. I need a run rate of 10,000 dots per hour and 99.99 % dots +- 10% volume. Equip

I've been running an eval on it for a little while now. Most impressive thing I've seen so far: Dispensed 100 grams on stencil, printed two solder paste eval PCBs and reflowed, put paste onto sheet of FR4 and let it sit out in the shop next to the

SMTNetters, I have a product coming down the pipeline that we'd like to make pure double sided reflow, it'll be RoHS product, and the hope is... we'll be able to solder the thru-hole stuff by screen printing solder paste and reflow soldering. Anybo

the flux in the solder paste should take care of the oxides. if possible print a board and run thru reflow to check for wetting issues......there are some published papers that say that the tarnish layer is too small to create any wetting issues or o

Hello, We have problems with insufficient solder volume on a component. To solve this problem, we want to add more paste to the component. We have two options for this: 1. run a stencil with a step to achieve the required volume. 2. overprinting
