Where to find a small clamp for reballing SMCs?


Hey all, curious if anyone knows where I can find a small clamp for doing things like SMC reballing. I've seen mention before of a store called Precision Rework, but I can't seem to track down anything under that name (perhaps they've since gone out of business), and I've tried 2 cheap ones off Aliexpress but the size as compared to the photo is huge (one I got is the size of an iPad - not useful for small chips lol). Thanks for any help you may have!
