Our machines can place components down to 16mil, I've never seen any finer pitch components in use, what pitch are they going down to now? 12mil??? What pitches have you been using? We are a contract manufacturer so customers sometimes supply free

Hi Dave, Was planning on skipping the paste step & screen printing the adhesive straight onto the pad, then placing the component into the glue & curing. (Board has LEDs only) Regarding the lead-free HASL issue - not entirely sure on the board man

Would these be the parts that have just pads located on the bottom of the part? If so, we place these every day in decent volumes and have never had any manufacturing problems with them. I cannot comment on the reliability since we are a contract M

Yes we've had problems with kemet caps on 12mm t/r. By the time it gets replaced, our production schedule gets so screwed up. Our immediate solution was to bypass and place them by hand before reflow. We eventually went with a cross from Venkel and i

With twenty five machines working with the LFB227/S on our little island it does seem to work well. Wetting is good compared to Tin/Copper and flow is comparable to 63/37. Biggest problem sticking 3 - 4 % Ag in a solder ignoring the patents and royal

i have a bit of a problem. i need a 320x240 lcd with a 5.7" screen, and a max width of 146mm. i have checked with about a dozen manufacturers and 148mm is the smallest they make without custom designing the pcb, and this is prohibitively expensive. w

If there's no shear strength standard for solder joint, how will I define my pad width and length then. I have a 8.5 mils width and my component lead width is 8.66 mils based on manufacturer's minimum width specification. How will I identify that it

Thanks for the reply, Russ. I looked at the Air-Vac web site. I am looking for something that is a lot more basic than their machine. I had seen a small table top wave machine at a customers shop a few years ago. It had a pump and different si

Hi, I don't know if I'm being naive, but I'm seeing a number of 3 zone (+1 cooling) ovens on the market that claim to be for Lead Free soldering. Trying to follow component & solder manufacturers ideal profile can be tricky with 7 zones at times so
