Charley, I dont know what you define as durable but the one thing that I know about the QP 242 made by Fuji is that its slow and a very clumsy machine. The QP 242 is what Fuji calls there modular concept machine. I dont know about you but when I hea

WARNING: This is a plug. I have read post on this site where the question is raised: "My machine can do 80 units per hour, but I am only getting 35 - WHY?" Well I have written w95/database code that reads FUJI output files (CPII,CPII,IP2 etc) and d

We have just recently started using the Overall Equipment Effectiveness (OEE) metric on our SMT lines. This measurement is the "equivalent percentage of time the equipment is being used to produce saleable product at the maximum machine rate." The

Tombstoning is often caused by non-uniform heating. I suggest you check you profile to ensure you still have uniform heating and also check your rise and cool rates. If you have a convection oven I would look into the fan speeds or airflow rate throu

I have oftened wondered how this industry lets its workers get away from being responsible. The best way I know of is to have them buy their own tools. Just take a look at the trades - carpenters, plumbers, welders, sheet metal men, body repair, mech

Fuji: Wonderful machine, very robust, Hardware second to none. Lacking on software Universal: Love the GSM, great platform. Sanyo HSP�s are ok, like the new 4796, not sure about the 4797 yet, have not had it long enough to give good data. Sieme
