Hi Chrissie, This might be old news to you but I just wanted to make sure that you are aware of all the implications of BGA rework relative to the control of moisture-sensitive components. For example, you need to keep track of the total exposure t

I am not sure if you have already approached Universal with your request. Our platform product team has a long history of integrating bowl/vibratory feeders with the various platform products. Typically, these are custom solutions configured to meet

Hi Chris, Yes there is a limit to the bake cycles : "...the cumulative bake time at a temperature greater than 90C and up to 125C shall not exceed 48 hours. If the bake temprature is not greater than 90C, there is no limit on bake time..." Ref: J-S

Tough to say. It depends on the type of solder mask, the producer of the solder mask, and your board fabricators' process. As one angle on this, solder mask type affects thickness. Minimum clearance: * Liquid photoimageable: 2 thou * Screened liq

The camera is not driven from the motor cards. The camera is attached to what is called a forcer. For the Y axis there are two of them. One is wired backwards from the other. one of the forcers is connected to a flex chanell for the air and electrica

Hi Serge, First of all: "i HAVE to buy"...? Sounds like someone is twisting your arm to buy a piece of iron you're not really enthousiastic about... But on a serious note: I've been comparing some machinery myself (also with Pana and Siemens) and I

This string is near and dear to my heart and anyone who can simplify this process will be a hero. Our Production Lot Traveler started with the initial intent of being able to track lot splits (traceability) of jobs and who worked on them (accountabi

Hi, I think the comment about the board height is because the MYDATA checks the board height each time it loads a tool so this is eliminated from being an issue because the machine knows the PCB height. I don't think it's so much what height the PCB

I agree with prior postings, but there is no perfect yes/no answers, right (left)...? Only good questions to be answered. I think it is overkill to have an extra stencil, why do you need it? (That is if you have a proper stencil cleaning equipment).

Greetings all, Dross has no value to the assembler. It actually degrades quality as a clean solder pot provides a more consistent process. Yes, removing dross does remove some metallic contaminates but that is overkill, like throwing away your refrig
