We are a low to mid range manufacturer as well. I looked at several different vendors incuding; Mirtec, Viscom, Marantz, Omron, VI Tech, Orbotech and Yestech. We selected Mirtec. As a mid range manufacturer, one of my main concerns was quick and eas

We are currently using an ACE K.I.S.S. 104. We used SN100 solder with AIM NC265 flux (no clean, alcohol-based). Also, we use topside preheat at 100 degrees C and a 6mm nozzle (as big as we can go with this application). The PCB has a matte finish as

I have had Selective issues such as yours on two very different Selective Solder Machines. I was able to eliminate these issues by using Alpha EF-9301 wave flux with any SAC305 solder. It's a more aggressive flux, but really made the difference. Anot

Good morning, Just a few questions to clarify: 1. You backed up your machine proper data. 2. You upgraded Fuji Flexa. 3. You re-transmitted the proper data 4. Now, components are not placing properly? Do you have a fuji 96-001 calibration board? Ha

Our Customer had detected tarnished pad on ImAg PCBA and had conducted several SEM-EDX test at the soldermask below some of the chip resistors. High concentration of sulfur was found and it can be significantly reduced after further chemical cleaned

Hi guys, I need your advise on this, I have a very uncommon PCB design (at least for me, I've never seen anything like this...) it is 32" x 18" x 0.062" and has 9 QFNs that are driving me crazy, I'm not able to get a good alignment, I can get a mediu

Hello: We have used our Phillips Topaz on a number of volume jobs and been very pleased. A while ago it became apparent that the vision LED's were growing dimmer as evidenced by having to adjust light intensities upward for various components in so

Hey guys, I'm new to this forum and registered to ask a question about PCB assembly cost. I was hoping to design a PCB that will be approximately 6" by 6" with about 1100 0805 SMD components on it. Half of them being resistors (3 different values) a

Maybe the area ratio between the sides of the stencil apertures and the aperture opening is too low for the spec of the paste ? So it will tend to stick in the apertures. ...only solution is thinner stencil or a paste that can release easily when are

Hello all. I'm having a bit of an issue with my IVc that's driving me insane. On occasion when placing a part, the machine will consistently reject the part 3 times before adjusting and then pick and place the part with no issues. I've done everythi
