Hi, You can go a long to answering that question yourself - what do you need to see? If you are lookig for the normal stuff like bridging, opens and voids you dont need anywhere near 130-160kv. I have just completed the same excercise and we have s

I'm having an issue with a particular board we run in our wave solder. it has a USB connector with 4 pins that are 3mm x3mm square. we are constantly getting abridge across at least two of the pins, but sometimes all 4. I've run out of ideas on ho

I would suggest that the pad size vs lead length vs lead pitch are helping cause issue if rest of PCB is ok From DFM , yes reducing lead length - experiement or reducing pad diameter could help. Also flux can still be issue, try fluxing part prior

Question, I'm new to this equipment, and have been asked a Question that has me stumped. When calculating the square area for a CCA to determine the volume. What do you do if it does not cover the CCA? I have read the manual and it state that the vo

If you don't submerge the board, how do measure the level of contaminants on that portion of the board that is not submerged? I suppose that you could only submerge a portion of the board and guess that portion represents the whole board. Of course

We are using Ekra Stencil printers and they are great except for 1 problem... We run several different boards a day and we need a way for the operators to place the pin supports in the same postions on the second side of the board everytime a board i

I would agree with Sr Tech..Grid lock and systems like this can be used on the Ekra, MPM and DEK printers also can be used in Pick and place depending on the density of pin. If you choose the method of printing out a 1:1 photoplot. Glue it to a piece

Simple answer is no, there is no universally acknowledged acceptance criteria. Some time ago, I started a spreadsheet with the acceptance levels suggested by various labs on the individual ionic species. All are relatively close in their individual

HI Guys, i am facing similar issues with this BT resin material too. PCB specs are 4 layers, Nelco400013, same Tg and Td. My PCB delam after reflow. The PCB has both side mounted with SMDs. Initial mounting on the btm side after reflow, no delam. B

I'm unaware of the machine. The approach that you're taking in trying to learn more about the machine makes sense. Since you're not getting many responses right away, consider asking your sale-type for a list of customers that use this product. Be a
