We used to use an APS Gold GF-120 before we went lead-free and the HT version came out. It worked fine for low volume and proto runs though not as much control over the profile as an oven with more zones. We actually had a batch oven from Bomir befor

Hi Muarty, We've had a lot of experience with QFN's now. Several years ago we started testing various design methods of the via arrays as well as paste apertures to cover the arrays. There has been some time that has passed now since these packages

Hi, I have never been able to find an acceptable dispense process for dispensing small dots of solder paste. I currently have an auger screw automated dispense system and can not accomplish 0.010" dot sizes. In addition, stencil printing is much m

First, I would inspect for lack of solder bridges from the center slug to the outside leads. I would then look for evidence that the solder paste has reflowed beneath the component, without leaving too much void percentage. Typically we allow up

Hi I do not work for a board house but a manufacturing facility where we do a considerable amount of soldering wires to through holes. We pretin our through holes on both sides of the PCB prior to reflowing the solder and installing the conductor (w

In the same way my BMW gets me to work and back, it is a much different class (pricewise)than a Toyota Camry, yet both accomplish the same goal. Every day. Is the BMW a "better" car? Is the Camry a lesser vehicle, even if it gets me to work on time

If the machine is printing with an offset on all products, then yes the printer needs to be calibrated with the fixture. That particular model requires the same tools as the 500 and 1500. They were different from other MPM machines of that or prior

We've been running our ICOM 5000 off and on since it was new in 1996. There's not much help out there for this machine as Stoelting (who bought out Westek) no longer supports it. You might need to replace the filter, which Stoeling can provide, but
