: I have a customer who seems to be having issues making acceptable solder connections using the vapor phase process. Can you tell me if there are any specific issues related to vapor phase soldering to immersion tin plated pads on relatively thick multilayer PCBs? Answer

. These sheets are electrically isolated from each other with a layer of non-conductive substrate. PCBs are faster and easier to fabricate than earlier mass-producing circuits since fabricators can mount and wire components in a single operation

. Copper weights range from 1 to 4g. Finish plating can be leaded solder, or any following RoHS-compliant finishes: lead-free solder, immersion gold, immersion silver, white tin, or OSP

. The materials you use during fabrication will impact this as much as the finish. Immersion silver, immersion tin, and OSP finishes are, as a rule, more prone to breaking when not properly held

. This shuttle used PCBs in electronic systems such as control and guidance. Atlantis flew a total of 33 missions from 1985 to 2011 and used PCBs in control, guidance, and navigation systems

: Tin sweats are formed this way. Along with the process of volatile solvent being removed from the solder paste in preheat stage, solder paste gasification occurs

leave the soldering pad and some of them may hide under the chip components. When reflow soldering, these solder paste will melt and then be forced out from under the sheet-type resistor-capacitor units, thus forming the tin sweats. It can be seen from
