Hello everyone! I work into SMT branch, on p&p Faroad, Quadra TWS and Autotronik. I always mounted a lot of circuits, especially strip led on kapton sheets. I noticed that thing.. between a kapton circuit and another there are differences such as lit

What is the advantage of dispensing dots over dispensing a line? I don't see any reason why dots wouldn't work. You might have to experiment a bit to dial in the right volume and spacing to get the desired end result, but it shouldn't be hard. Fisna

Hello Dekhead, it is a constant offset, like 0.5 mm to right when machine prints away from operator. When print goes towards the operator there is no offset. I swapped X5 and X6 cards with spares I got but still same result . I set the program to hav

Hi Everyone, We've just bought a second hand Omron VT-RNS-pt AOI machine. It appears to work fine but we're struggling to understand how to program it. I have the set of manuals but they are not easy going, and it's going to take me quite a while

We have been using Cree 3 color LED's (CLV6A-FKB) in many products for several years (pic attached). At the rate of 3 to 5% of the units assembled with this LED, the Red LED fails. After touch up with soldering iron it functions. This happens to the

We've been getting more and more flex and rigid-flex assemblies. Making carriers for mounting the boards to go through printer and pick & place is becoming more challenging with the size of some of the arrays. Normally we use a pair of pins tha

It's the printing part that's the most challenge, right? You can print it correctly, then you should able to run it with PnP. You might need to have one "print" fixture only for screen printing, then transfer the printed board to SMT fixtures which

I presume you mean at microwave frequencies. If not get it right in the CAD. Programs such as Microwave Office and VSS make it easy. Also Ansoft, Keysight Eagle etc. Having used MO and Eagle I would heartily recommend them. In the bad old days one tr

You can try putting titanium stiffeners on the PCB to prevent it from warping. How thick is your stencil? More paste would give you a wider window however too much and you risk bridging. You could try over printing the pad at the heel and toe to get

I think Steve is on to it. The wire is not getting hot enough to wet. Either the solderer is attempting to solder too quickly, or the PTH is connected to a ground plane. The solder sticking up through the hole leads me to think it's connected to a
