Vanstron – Vertical Cooling buffer ( FIFO,LIFO,BY-PASS)

Vanstron – PCB HANDLING EQUIPMENT – Vertical Cooling buffer ( FIFO,LIFO,BY-PASS)

Product Introduction

This vertical buffer is designed to have the function as FIFO/ LIFO and by-pass functions, which can be located between SMT machines to improve the working efficiency by buffering.The system is available to carry on with the FIFO ( First in first out) or LIFO ( Last in first out) under the programming time mode; Cooling fan with programmable cooling time. This vertical cooling buffer is very good to put it after the reflow oven as a cooling buffer.
