Mike, To answer your question, Yes we have thru-hole parts on the boards that we converted to double-sided reflow, we use pallets to select solder the leads. I suppose Masking would work, but that's using a lot of mask. Can I ask, whats preventing

If the thermal mass of the products is small, a tent-shaped profile is recommended, with peak temperature around 240C. The hottest spot on board should be less than 250C. However, if the thermal mass of the product is large, such as a large server PC

Steve, KIC does. The new KIC2000 has built in dwell time sensors. You can buy KIC's wavesurfer option (like MOLE's waverider), or you can engineer a custom pallet for 1/3 the price. I made a custom pallet and took advantage of the KIC's automatic

From what I can gather, the annular rings are used for grounding when these boards are put in housings. A screw goes through the hole and is torqued down. If there is excess solder on the annular ring, the screw doesn't seat properly. The pallets cov

Valerie, Thank you for your reply. I have a quick question......when you converted to a double reflow process did you have any thru-hole parts on the assembly. If so how did you handle them....pin and paste? Thanks, mike

I have expirence running,double sided Imm gold boards recently which ed up a lot of solderability issue. The Imm gold need to be slightly more control during reflow oven area on it's profile.

Headers and SMT

You don't say how many headers you have to solder. I usually spec in High temp headers and use a pin-in-paste methodology and double reflow. Can you get your headers high temperature?
