| Dear all, | | What are your views on reworking BGA's? I mean, with the BGA going through reflow temperatures four times or more, and with a manual reballing process, wouldn't it raise up a few reliability issues? Would you consider not doing rew

Hi Clarissa, seems to be a real start up situation you are in. For the printing there is IMO no need to buy any sophisticated automatic-vision-alignment-self-cleaning-inline-and-more-machine. Features you need: - adjustable in X-,Y-,Z-axis (individu

We currently have 32 LEDs per board and are looking to change the LED from a gull wing package to another package. (possibly a chip type package). I have heard that some cases and LEDs do not like reflow. This part is not cost effective to have to pu

John, I sell preowned and reconditioned PCB assembly equipment for a company called Insertech. We would have several pieces that would meet your needs and were typicaly 40-60% lower than the cost of new. If your interested in recieving any info.

Grant,You should take a look around at all of the alternatives out there. There are many fine solutions from every SMT assembly vendor. Fuji is not the only game in town. You should not purchase on name brand alone. If you are considering the CP-7, I

So how does this (lead free paste Sn42/Bi58) solder compare with the Sn-Ag-Cu (Tin-Silver-Copper) combination which does not flow as well (in the oven), needs higher oven temperature, (that can be adjusted by reducing the oven chain speed) and cost m

Multiple process and rework thermal cycles are brutal on boards and components. Improving reliability of products through reducing thermal stress ends-up being a major driver to the interest in lower MP LF solders. Binary LF solders require the addit

Maybe this piece of information will help. In China (just returned from visit) there are many factories that are using a dual temperature process using SAC305 or Sn100C and 42/58. Apparently this allows them to run their through hole parts through re

Hi guys we had problems with our old pick and place machines and all the parts data and mark data was lost when we had to restart the machine. We made a copy but it has been so long that we used it that now it's not working. I hope someone has one of

Clarissa, Buying used equipment should not be risky if you do your homework. As M COX said, you should find out if the manufacturer still supports the machinery but don't take everything they tell you as gospel. Remember, they want to sell you a new
