I am aware that the Intel processor is available in a 0.012" leadframe, as a TAB product ( which can be excised and placed with may P&P machines but I do not know of any 0.008" leadframes, Bumped Die are at these pitches and frankly I would bet dime

Do the parts sit directly on the PCB? Typical 2.0 mm Max is desired for the component to be off the PCB. Are stand-offs an option? The long lead wiggles as it passes through the wave and thus agitating the air out.Does your wave a "dancer" option?

We build a mixed tech [eg, QFP, SMT fly shit, DIP] board where we can't clinch the DIP. So we set the clinch and cut on the DIP to just barely clinch, leaving the leads very perpendicular to the board. I wonder if you could do something similar wit

We had the same problem years ago when we started using a radial inserter. The inserter would dutyfully insert and clinch the leads. The problem in our case was the component body sealing to the fab, especially on electrolytics caps with a film jac

Wow. Never have, never would, but that doesn't mean it couldn't be done. Mostly it just seems impossible to design a carrier clip that could hold both well...more likely it would hold one well and the other poorly, or both poorly. Anyway, is there

Manufacturing already tried to get a design change but no chance. I guess because the designer is afraid the components could get bent too much if they are mounted with a stand off. Of course everyone who has to manufacture this fist sais: why don't

On mixed technology PCBs, we find numerous blow holes on the solder joints of radial parts (electrolytics, LEDs, etc). The solution that works so far is to cut the leads very long in the radial inserter so that the part is kinda loose and the air in

Hello all, we are about to modify a Universal Radial 5 so the machine will be able to insert radial components with lead pitch 3.5mm and 5mm. The 3.5mm components are ELCOs which are getting inserted all the way to the component body so they sit fi

I have worked with Radial II's, III's, and V's. Every one had a verifier, but none of them ever got used, primarily because of the false failures.

we have 3 Rad 8's and never use the verifer cause its too bloody slow.Why bother u cant verify parts being placed on a chip shooter so if your operator takes the same care when loading a reel there should be no need to verify.
