We do support components in both reel and tray format.
For more details, please refer PCB assembly capabilities.
For manual assembly we accept components in reel, tray or even cut tapes.
For automated assembly components can be supplied in reel, tray or cut tapes but the minimum length of the reel/cut tape has to be 10cm.
Tapes are commonly used with larger SMTs, like QFNs and BGAs.
