Industrial Dispensing and Potting Knowledge Center
The OBO Precision knowledge center is the fastest way to understand how this site is organized. Instead of browsing dozens of unrelated articles, you can

Complete Guide to Dispensing and Potting Material Selection
Material selection is one of the highest-leverage decisions in industrial dispensing and potting. The right chemistry can make validation easier, reduce defect risk, and simplify

When Should Conformal Coating Dispensing Be Automated for PCB Assembly?
Conformal coating does not need automation just because the product is electronic. The better question is whether the board complexity and production expectations have outgrown

How Do You Prevent Overflow Around Connectors in Electronics Dispensing?
Overflow around connectors is usually a boundary-control problem, not just a volume problem. In electronics assemblies, the local interface shape and stop behavior often matter

How Should Engineers Program Dispensing Paths for PCB Assemblies?
On dense electronics boards, path design is often as important as the dispensing hardware itself. A stable machine can still create defects if the path

How Should Buyers Evaluate PCB Glue Dispensing Machine Suppliers?
The easiest way to buy the wrong PCB dispensing machine is to compare vendors by brochure accuracy alone. In electronics assembly, a supplier's thinking about

How Should Engineers Validate PCB Dispensing Before Mass Production?
A few good-looking boards do not prove that an electronics dispensing process is ready for mass production. Release confidence comes from repeatability, sequence control, and

Underfill vs Corner Bonding: Which Fits PCB Assembly Better?
Underfill and corner bonding solve related problems, but they do not behave the same way in production. Choosing between them should depend on assembly risk

How Do You Prevent Stringing in Electronics Adhesive Dispensing?
In electronics assembly, stringing is more than a cosmetic annoyance. A small tail can contaminate nearby pads or components and quietly lower yield long before
