There are several alloys had been using in the industry. For SMT: most people use SAC305 For Wave: most of them use SAC305,SC100C,SCS7,and SACX0307. Of course, different alloy composition have its own recommended profile. There is no such rule tellin

Hi, which kind of stainless steel are made your solder pot components? for istance : AISI-304 ? AISI-306 ? AISI-312 ? AISI-316 ? As we know AISI-316 will last more against Tin erosion. But AM SACX does not allow so much !!! I know who since t

The Philips Orion (Yamaha YV100) Head I/O Board is usually at fault as this tends to suffer trackwork problems with age due to the constant flexing of the board stressing the connectors on the board, thus breaking tracks within layers. You should not

For ur information, this BGA machine was full utilize every day. I have more than 100 model to do profiling every week. Different PCBA with different thickness & material need different temp setting. currently i'm looking for profiler that more compa

Good calculation, i have to say. Do you forgot, If you let the machine cool down during night, the rest-temperature isn't roomtemperature? right, dont you think the temperature will be something about 140�C ??? heating up time then is not 3 hours. m

Hi Bart, I suggest you have a look at Assembleon's OPAL XII. They have a special offer at this moment. You can select the machine with 4 heads (standard) and later if higher speed is needed, you can upgrade it to 8 heads. the machine is capable of h

Never use a water softener for defluxing. They add sodium to the water which is bad for boards. The white residue may be flux. If that's the case, either the dishwasher is not powerful enough or the wash water is not hot enough. Another possibili

We have been producing an IMS assembly with SMT dpak's for some time. However, we recently encountered a new problem by chance - the parts can be flicked off with a finger nail. I state by chance because the solder joints are wetted and shiny with

Sup G! Normally when spray fluxers get neglected, the spray pattern is the first thing affected. To actually 'see' this, we cut out a piece of cardboard the same size and length of the board. Run it over the fluxer and then turn itover and look at
