I need to confirm you 2 , Are you discuss about top clamp problem with Jmli already ?
Now he confirm design by cutting pin clamp around 2 mm. only.
At bonding machine Gen1 , ACA clamp and Top clamp are shorter than Gen2 and don’t have up-down problem (Smooth up-down) / rusty problem. If you 2 don’t understand problem please review at front of machine again.
