Hi Eric, Every mounter have a standard count and "release" off the component. The sample and cost saving way is to use the paper (e.g: 4mil,5mil...thick) to measure. Just place on the PCB with supoort base below and release the nozzle step by

Is there a sort of standard method to prevent part loss in reflow? I've had a couple of situations come up recently where we've lost some parts during second-side processing. We're running an Heller 1800, with a mesh belt. Most items process fine,

We're aware of no industy acceptance standard for max moisture content of a board. For more on moisture levels, get a copy of: "Removing Moisture from Electronic Components and Assemblies", CS Leech, Jr, Circuits Assembly, May 1994. The article disc

Assuming your conformal coating material was selected with the intent of living a life in contact with oil, why doesn't your coating meet the IPC-A-610D requirement of that there be no voiding, no breaks in the surface, no loss of adhesion, etc? Furt

We are increasingly being asked to store components for longer and longer periods which we know through experience leads to reduction or total loss of solderability of the parts. 1) What is the industry accepted shelf life of tin/lead plated compone

| We are finding solder shorts under 1206 Components on the bottom side of our boards.In all cases these shorts are from either side of the component to a feed-thru under the component body. Adhesive is used to glue down the component and then the bo

Hi, Encountered this deference to the vapour phase process that was supposedly "phased" out years ago? *pardon the pun* Any comments from folks who have used this proces before? how about folks who are currently using this process? even better, a
