Chris, To my knowledge the only difference between leaded and lead-free components is the termination plating. What has changed in the component design that makes them resistant to higher temperatures?

Hi Jacky, It seems you have solder bead problem, beading occurs when the solder paste brick splatter as a component is placed into it, after reflow, the splatter becomes a spherical solder ball. Hope this will help. Steve USA STENCILS

Jacky, we have had a similar problem. We needed to go to a smaller nozzle and also check your vacuume system and air kiss.Could be after placement when the machine blows air to insure the part is off the nozzle that it is effecting the solder brick.

It's a small diode with orange core - has a blue kathode stripe it reads "3" then as you roll it over it reads "2c" That is it. I really would appreciate any help in identifying this diode and understanding the coding method used on these diodes. Th

I'm looking for some info on contract manufacturing prices. What is a ball park price per SMT placement? I figure there would be two types: Placement A (easy, 0402 and up) and Placement B (0201 and lower and BGA).

Component cost or placement cost? Hand placed or machine placed? If all machine placed, how big of a board? Panelized or not? Any thru-hole? Any shields?

I'm looking for placment cost on machine placed SMT parts. Circuit is 2"x2" on a 6up pallet array. Also has 3 hand placed thru hole caps.

I found a website that will let you quote your part online. Enter in board info and it calculates a price. They have it at .35 per SMT placement. That sounds very high.
