Thanks for the suggestions, Caurbach. We do have the occasional lead jumping out even at this length, hence why we've been hesitant to cut them shorter. I have the wave nozzle to PCB distance set as per the machine instructions (4mm I think?). I ce

| Can anyone recommend a solder stop that can be applied by our PCB supplier. Our current material form Tamura Kaken is causing problems. | | The material should be capable of withstanding 1 Surface mount IR reflow cycle and 1 wave solder cycle. | W

For the past year now we have been printing adhesive with no real problems. Our printing ranges from 0603's to SOIC using a variation of aperture sizes and metal thickness foils. The crucial parameters are : aperture sizes : These obviously depend o

Hi Buddy, We've tried shifting to this process before and from our point of view here are some of the advantage and disadvantages that we discovered. Advantage 1) Cheap Equipment cost as you just need to use your Solder Paste Printer rather than buy

Thanks for the replies. The single missed lead is a bit odd - we usually have an entire area missed and that's due to the board not sitting properly in the pallet fingers. I figured in this case it was likely due to poor fluxing? We have always str

Hi We are running automatic stencil printers, open squeegees, stainless stencil, stainless blades, print speed 25-30mm/sec. We have a frustrating consistency issue printing .37x.3mm apertures on a 45pin LGA (11 pads each side, 1 large ground in mid

Hello All, We have a small selective solder machine from RPS, a Rhythm SS, purchased used with SN100C in pot. For a couple of years we have used this machine and gotten good results. We have been adding SN995 to the pot as it needed more solder. Then

What your asking has many variables. 1. Material: SS vs. Cast Iron. Iron is thicker. Which SS? 316, 316L 2. Pump speeds, turbulence, hours of operation directly affect equipment life. 3. Things like scraping the pots, the tunnels, impelle

SPC was a fad of the '80's and has been mis-used by the igonorant for decades now! Doing SPC on defects is a case in point. Hell I implemented wave SPC programs before eating breakfast at 2 previous companies, and they worked great..resulting in 25
