Keeping thorough records during the curing process can save your bacon down the line, ensuring that future applications stick around long enough to avoid annoying failures.
How Can You Fix Those Pesky Problems?
Is your epoxy resin behaving like a rebellious teenager? Don't worry; you've got options. One common issue is the dreaded air bubbles. They pop up uninvited, often ruining a perfectly good pour. A quick fix is to use a vacuum chamber to degas the resin before pouring. This magical device draws out the air like a bad dentist seeking cavities. For those who prefer a DIY approach, gently heating the mixture can also help lift those pesky bubbles to the surface. Who knew it took temperatures hotter than a summer day in Phoenix to get epoxy to behave?
Sometimes, mismatched components can pull a stunt similar to a poorly cast sitcom. If your epoxy resin isn't adhering well, check the surface preparation. A clean, roughened surface helps the adhesive perform like it’s training for the Olympics. If all else fails, consider switching to alternatives within the realm of thermoset plastic examples, which may suit your specific needs better. Remember, not all epoxies are created equal; some bond like soulmate pairs, while others are just swiping left. Adapting your approach can keep your PCBs durable and functional, steering clear of those cringe-worthy mishaps.
