Thank you all for your input. The MF300S Multicore flux is rated for lead free. There is not much dross or contamination. We are using nitrogen. I've tested the boards with the curing test of IPC-TM-650. I think you're all right about the preheat.

Hi, I've just splashed out �60 on IPC-A-600F trying to find out the formula for measuring the bow and twist of raw PCB's. Much to my dismay there are 10 lines on the subject in the whole standard. Worse still is that it tells me nothing I don't alre

I doubt you will be able to get satisfactory results with 0201. 0402 is another story. When doing 0402 projects, we use only electric (MP) feeders and always at the same feeder slots (feeder teach done for each of them). MPF08 nozzle works fine. Also

We can offer several nozzles to assist with the placement of 0402/0201 components in the four-spindle head. We offer the 06MPF along with custom ceramic tipped nozzles. Most of our standard nozzles for this head type are less than $125.00 each. Chec

Thanks, Deni! We're replacing two 4-spindle GSM's with two GX-11S with Flex3 front and IL4 in the rear. These we plan to use a mix of our pneumatic & 24V feeders as well as high speed feeders as we acquire them. The sellers advised that the 24V kits

Hi Greg, We've used lots of machines over the years & seen lots of different tape related issues - the main one being snap off of the cover tape, usually due to too much glue, over entusiastic heat seal, or a feeder requiring maintainance. Also the

Thanks for the reply Rob, This we already do. The machine will pick from the most efficient available feeder (assuming multiples of the same part number)...so when you remove the primary it will seemlessly move to the next available. When you re-in

EricR: Regarding "*** By the way, since we have used the Tin-Silver-Copper lead free solder there has been a strange liquid type chemical leek from the oven exhausted pipes." ... I don't know anything about your process, but the first thing I'd inve

Dear Chris Thank you so much for the prompt reply and it really helps. Do you have any SMT experience for rig-flex boards? Can you share with me about the differences with that of rigid boards? Is there any special precaution needed? When you were d

Don't sound proper. There is no specification. Pad peel strength test methods are: * IPC-TM-650, Method 2.4.21 for multiple solderings * IPC-TM-650, Method 2.4.8 for copper peel with a Instron machine. Typical requirement for Cu is: 6 lbf/in [1
