I am sending my first PCB design to Sunstone for manufacture and I need to decide whether to order the board finish lead-free. All of the components are lead-free, and I have not decided on solder paste. There are about 25 chips on the board and the smallest are 0803 and SOT143. The board size is 3.0x1.5 inches. I am planning to order a cheap IR reflow oven like the T962A. This is not a consumer product (it's a driver board for an IR laser used in scientific experiments). I understand that lead-free solder doesn't flow as nicely and requires higher temps, etc. Shoud I Go Green or should the additional usage complexity dissuade me from using lead-free?
Followup question: should I order a stencil for a board like this?
