1%-3%RH Dry cabinet is especially designed with fully automatic humidity control to prevent moisture related damage. This cabinet is the optimal storage expert for humidity sensitive SMT/BGA/PCB/electronic components. Symor newly-developed design greatly increases dehumidifying system which runs faster and more reliable by comparing with those traditional dry cabinets. It can decrease the defective rate at production line. All Symor manufactured dry cabinets comply with J-STD-033B standard.
In SMT manufacturing process,moisture is absolutely a killer for PCB/IC,during the heating process, the PCB/IC(e.g., PBGA, BGA, or TQFD) is likely to crack and thus cause non-effective welding because of the humidity, these MSD will be damaged by moisture immersion during production line and also inappropriate storage.
Powerful desiccant(free exchange) inside cabinet absorb and exhaust moisture automatically, together with advanced IC timer, memory alloy and heating module, the whole cycle repeat automatically, so the inside humidity lowered, the humidity is controlled by LED controller.
This curve shows that under ambient 25 degree C, humidity 60%RH, open door 30 seconds and then closed, the humidity will recover to the setting value within 30 minutes.
