Hi Eric, Every mounter have a standard count and "release" off the component. The sample and cost saving way is to use the paper (e.g: 4mil,5mil...thick) to measure. Just place on the PCB with supoort base below and release the nozzle step by

Guy,s I do not have Red-e-set, but Grid-lok offers a fully automatic system that easily installs onto the printers and P&P. It can be set to your board instantly by pressing one button or triggered by the printer to set for each consecutive PCB. They

Curiously... Shelf-life of the plating alternatives has been mentioned several times as a potential issue in these discussions. Tell me is there a market for a simple plastic packaging which could extend shelf life (and hence solderability) of these

Hello Chris, "It sticks up about 3/8" or so above the surface of the board." Is this over the ridgid portion of the PCB or in between? Is it possible to create a support fixture for printing that has relief that will allow the flex to bow downward i

Our company laser re-ball's BGA down to 100 microns ball size. One of our OEM customers have asked us to function test there BGA on Mobile phone PCB's. Origionally we thought of a test sockets however the sockets interfere with other devices on the P

Hello, We are assembling a large pcb with 256 Lumex #SSL-LXA228SRC-TR31 SMT LED's on an HSP 4791. The part I'm using for the library is a modification of an existing SMT LED from the standard library. The problem is that the HSP rejects about 30% of

You can also try the Florida Circtech website or call them direct. There is a min. thickness requirement and if the board house does not follow it you will end up with scrap boards after the second pass (from experience). I even sent blank boards to

Anybody have any ideas on the proper way to screen solder mask onto a PCB? I am going to cover SMT parts that were soldered to the btm side of the PCB, now I have to mask them in order to run this animal through the wave solder process. I know it w

i have a bit of a problem. i need a 320x240 lcd with a 5.7" screen, and a max width of 146mm. i have checked with about a dozen manufacturers and 148mm is the smallest they make without custom designing the pcb, and this is prohibitively expensive. w
