>We have looked at a few, and some use the removal time to >>calculate the placement time, which seems like a good idea. The problem with this method is that you can't develop an accurate removal/installation profile. You are removing a component a

We are also using Vapor phase for our process. We currently have 6 profiles that we have established. 3 for Leaded and 3 for Leadfree. We have set-up our profiles depending on the mass of the board. We do have some tombstoning depending on several va

Does anyone have a good answer to lifted components? I read on this site (old thread) that someone designed bean bags to set on top of a PCB to keep the components down on the board. I know that seems like a short cut to eliminate lifted components

Hi Indhu, It could be multiple reasons but probably one root cause. metal nut might require reflow profile change- you need to check it with SMT reflow profiler. the part might be oxidized - you can check solderability or try to solder part using a

Most people do not intend to �solder� Type K thermocouples. They use solder to �attach� the thermocouple. Search the fine SMTnet Archives for a posting by Chrys Shea. 1 Common thermocouple types commonly used for thermal profiling are: * Type K �

Russ: You've got stop soft-peddling this stuff. This doesn't sound like "poor solderability." It sounds like "no solderability." It also sounds like you�re dead meat. Three places to call: 1 Board supplier to get their suggestions on unsolderab

This is a used oven, new to us. No product has been setup on it yet. We were establishing som baseline profiles and noticed that the actual profile read didn't even come close to our optimal profile. Further investigation proved that the belt was to

We run Mascots for leaded assembly on 15 stations for 20 product types in around 2500 variations...the system works brillianlty for us, but we experience programs going out of sequence for no apparent reason spontaneously - literally, an operator can

Hi all, We have two Heller ovens, a 1700SX and a 1700D. The 1700SX has the profiles made so when you load them the zones turn on in sequence. First zone top and bottom are on when the profile is loaded then the next (top and bot) start to turn on as

Vapor phase soldering systems by Asscon are characterized by special designed heating modules. The thermal mass of the heating modules is designed so that a completely delay-less and direct regulation of the heat/flow/energy transfer to the soldering
