Hi, what kind of issues i could get if the i do not provide heal properly in my footprint ? In my current design 0603 resistor package footprint heal is missing by 3 mils each side Please help

We have recently begun using X5R dielectric capacitors. Although they have a better temperature coefficient over Y5V, they age much faster (5-7% logarithmically per decade). I assume the reason for using the X5R was the availability of the capacita

Sounds like someone before you was dealing with tombstoning components. We have had greater success with triangular paeratures for 0603 and 0402 footprints. Granted the pad will not be wetted completly but IPC requirements are maintained.

Hello Guru's, I am using IPC-7351 LP Calulator to design Footprint (0603, 0805, 1206, SOT-23, etc) for all SMT Parts. Our Production Recently commented that they have included Red Glue Machine inhouse and will use Wave Soldering for Both Thru-hol

We're trying out 0603 packages on some 0805 footprints (at this stage only on some test boards) since our vendor tells us the 0805's are going to be getting harder to get, and more expensive to pay for. I understand the IPC footprint for the two is

Hi Mika, I used to work for the largest chip cap manufacturer in the world, and by far the largest problem we would see was cracking due to incorrect z height adjustment on Chipshooters. It can also cause solderballs and bad joints by displacing th

Hi, I can give my opinion in this topic since I worked with both machines. To say the truth, I would recommend neither machine. First of all, operating software is much quite the same for both machines. The TP9 is true that has a larger footprint ov

Hi all, This machine is pretty good. Thanks to all that have been helping me out with this. I have another question ... Some PCB have footprints that are a bit larger than the actual part (0805, 0603) so they move when they go through the reflow ove
