I like this definition the best. After years of sales of pick and place and other, this is always still a topic of discussion. If your customer's cycle time involves building a board in two different machines, then I would suggest measuring and add

We currently are building a pcb that has gold fingers, about 36 in a concave V overall shape from .275 on the outside edge fingers tapering down to .197 in the middle of the 2 inch span that plugs into a shelf connector. These fingers are on both sid

Well, We have several lines some products run Kester 256 and others run the Timura. I have changed the product to print on another printer and it follows. We have several products that use the same paste and similiar board design that has a problem

Hi John, Depending on your board, it could make a difference. Copper finishes might leave that part of the pad exposed, which is a no-no in most places. Where as a HASL board prolly won't care if you pulled the print back. On the other end, over

Good morning, (1) This depends on component type. In general it would be better to have fully populated board. Or at least you should mount components with different thermal mass. You should place TC�s at three points at least: component with high t

>>> Now you must take into account your total board mass as well. If you have tons of heat sinks, or parts on the other side that can affect your profile, you should have them on the board when profiling. That�s where the "engineering" part in all

Set Up Guy, I am not sure if the COB you are refering to means Circuit on Board . If yes, this process also include SMT . Package is a combination of some passive components and bare die. Passives are normally attached thru SMT using solder te

All, We have ran a few revisions of a New Product which is a tracking device using satellite navigation. The protos went well but now they have added a shielding can. We place 2 of these to cover the Frontend of the PCB. The test guys are having d

We're in the process of trying to select a rebuilt, refurbished, or well serviced flexible placer, something that's capable of placing in the neighborhood of 10k and up. We're a high mix low volume shop so easy setups is key. I'd be looking at a MY-9
