I would go with wire thickness + 0.4 to 0.8 mm for pad width, and pre-tinned lenght + 0.5mm what seems to me like problem is that it can easily roll off the pads in reflow oven

Stencil thickness is 4 mil. Via's are plugging from bottom. Gas may be developed under the component? Take Reflow Ovens Thermal Profiling changes? In your opinion?

Can anybody suggest how to reduce 0402 LED tilting as I am using Convectional Reflow oven with 10 Heating zones and controlling the solder paste with 4.2 mills paste height

Do you mean in a reflow oven or wave solder? if so check your exhaust blower, make sure its still drawing. if not the flux/dust that builds up on the exhaust pipes may be falling into the machine.

What pick and place machine do you recommend under $20,000? I would like to be getting 8,000-12,000 cph reliably and without much maintenance/labor/issues.

I can get an Opal Xii for $19k or Juki 760 for $8k. Which one do you recommend? Both come with enough feeders.

Not yet, but also have an option for a Universal GSMxs machine for $6k but only 5 feeders, fully upgraded 2 heads (1 brand new). I leaning against the Opal as its same speed as the Juki on paper for twice the price.

What do you think of the Hanwha Techwin placement machines? I like their cph ratings but not sure how reliable and long lasting their machines are.

Would you prefer a Samsung CP machine over a Juki? I like the CPH figures of the SM machines and would think about buying one used once I am up and running 100%.

The L Version is slightly bigger PCB handling capability. However, it's relative to Juki, not to other manufacturers. We have found that the extra large board Juki's are similar to our standard Yamahas. Don't know about the 760, but the 2060L is 41
