Shelf Life Before Conformal Coating
Prior to conformal coating, how long can we keep a circuit board assemblies in an open condition before they will be impacted by moisture absorption? Listen as the Assembly Brothers cover this topic.
Channel: Adhesives, Coating, Dispensing
Solder Paste and the 5 Ball Rule
For either Type III or Type IV solder paste, should there be a minimum number of solder spheres deposited on each surface mount pad?
Channel: Assembly, Printing, Pick & Place
The Demise of the Plated-Through Hole?
How long do you expect the industry will continue to use through hole components? I can envision connectors being used for some time, but what about the other component types?
Channel: PC Fab, Board Design, Laminates
Problems With Wave Solder Lead Bridging
We are wave soldering very close pitch through-hole components and see bridging. Is there anything you can recommend so we can reduce bridging on this component?
Channel: Soldering, Selective, Wave
Removal of Oxidation from Bare PCBs
What would be the best method or product for cleaning bare PCBs that have a small amounts of oxidation? I know that proper storage and handling may solve the problem, but what would you suggest?
Channel: PC Fab, Board Design, Laminates
Is Baking Required After Water Cleaning?
Do circuit board assemblies need to be baked after routine aqueous cleaning? If so, how long and at what temperature?
Channel: Cleaning, Washing, Solvents
Poor Wetting On OSP Coated PCBs
We are experiencing poor wetting on one OSP coated PCB using a lead-free, no clean paste. We see this problem on just one board part number. Where should we look to solve this problem?
Channel: PC Fab, Board Design, Laminates
What is the Shelf Life of Solder Paste?
What is the practical shelf life of a syringe of solder paste, and what symptoms would one see when the syringe is getting too old?
Channel: Solders, Fluxes, Pastes
When Is It Time to Replace a Squeegee or Stencil?
Is there a recommended usage rate for stencils? Is there a way to determine when it's time to replace a squeegee or a stencil?
Channel: Assembly, Printing, Pick & Place
What Causes Chip Blow Off During Reflow?
What can cause a 0603 passive component to blow off the circuit board during reflow as if a firecracker was put underneath?
Channel: Reflow Soldering, Profiling
