Plastic Welding: Methods and Ideal Applications

In the not so distant past, there were limited choices for welding plastics – i.e. gluing or vibration/ultrasonic welding; and while both have their advantages and ideal applications, they are not up to the task of handling today’s smaller and more sophisticated product designs that use plastics.

It can be confusing to compare typical plastic welding methods and determine which one is best for joining plastics in your product design application. In this post, we’re going to give you a quick Plastic Welding 101 tutorial on the pros and cons of each type of plastic joining process and provide you some guidelines on ideal applications for each.

Don’t Let Your PCB Design Dreams Die – Rapid Prototype Them

That nirvana state of ideation – when the virtual light bulb comes on over your head and illuminates a new PCB design for a next-generation product – makes you want to jump up and create it NOW! That’s where PCB prototyping can put you on the fast track from ideation to creation of new and advanced PCB designs. There’s nothing more satisfying to a designer than holding a working prototype in your hands, testing it and seeing if it works the way you envisioned it. Right?

UV Laser Depaneling: The Clark Kent of PCB Manufacturing

Unique_PCBLike the mild mannered reporter, depaneling doesn’t stand out in the crowd compared to PCB design, circuit etching, and component placement. But depaneling is really an overlooked potential superhero in the PCB manufacturing process. Do it right, and you can meet or even increase production yield goals and rule the plant floor. Do it wrong, or do it with the wrong tools or process, and you could end up being the villain with damaged components, too much waste, and not enough production yield.

The Future of Laser Plastic Welding is Transparent. (It’s time to leave the adhesives behind).

Pumps, catheters, diagnostic valves . . . when you’re combining clear plastic parts, major headaches can occur. Traditional laser transmission welding requires one half of the component being joined to be laser-transmissive (allowing laser light to pass through), while the other half is laser-absorbing, thereby creating a surface which can melt and create a bond. The challenge when welding two clear (and laser transmissive) pieces of plastic together, is that the laser light simply transmits through both halves of the component, as there is no absorbing material present to heat and melt in order to create the bond. But solving that problem created another.

Looking to truly complete your PCB engineering lab?

Release your creativity with an in-house prototyping machine.

Ever see those posts about “life hacks” – how to use common everyday things in new, creative ways? Like using a gum wrapper and a battery to spark a flame. (A bit useless unless you’re stuck in the woods, but you get the picture.) At LPKF, we see our engineering customers using our PCB prototyping machines for a lot more than just what they were designed for. What’s more, they are saving significant time while boosting their creativity by not having to send out prototype jobs to a PCB or other fabricating vendor.
