Interesting, we have a SMT division, that caters to the exact scenario you depict... Actually am also trying to determine, a system of answering "high mix, low volume" picture... Just my humble point of view, dun think there is "best" system in th

3 Printer Area Conditions * As stated earlier, heat and humidity are damaging to solder paste. Ideally, the printing area should be maintained at 40% - 50% relative humidity and 72°- 80°F (22-26°C). In addition, no air (cool or warm) should blow dire

Yes, you must thin Dow CC for any spray operations. We use Dow 2577 daily for multiple customers and we always thin it for spray operations and 2577 is considered medium viscosity. Dow recommends using up to 60% solvent (Xylene). Your 2620 is low vis

That the bubbling gets worse when you run the board through the oven indicates the issue is with the balance between releasing volatiles and cure. Try one of these ideas: * Adjust the atomization pressure, nozzle size, temperature or viscosity of th

We recently experienced a problem w/voids (up to 65%) in uBGA solder joints. The only joints that have the problem correlated to pads which had blind 0.006" via's in them. The via's only extend down 2 layers, of the 18. 21 BGA's on the PCB, only expe

Hi ! The main problem being faced currently is formation of solder balls - to be precise, these are micro solder beads generally found attached with bodies of SOTs, Chip Caps, Chip Resistors, between pins of SOICs (50 mil) - lying on PCB surface,

Always wondering what kind of support can client and customer relationship can be in SMT market? Being in the SMt market for so long, customer does not help much but wanted more profit and low cost. Speed does counts but relationship play an importen

Obviously the cost difference between only smt and smt+th is huge though TH only 1 components,they need different material,machines,tools and control methods,so if possible just use only smt process to assemble all components,but to verify if the usb

Could someone point me in the right direction as to getting some information on SMT. I'm doing a final year project which involves some design of SMT. I have never done it before so I probably only need some basic information to get started. Anyone w

Does anybody know if you can get low cost RFID devices suited to the SMT manufacturing process. I am looking for a way of tracking PCBs without using barcodes, instead I would like to use RFID technology.
