Also we have just made a prototype for Wave soldered SMT components D-packs + 0603 + TSSOP�s on the bottom side with THT comp. on the top, the stencil manufacturer gave his personal library of glue stencil openings and adviced on stencil thickness wh

Hi guys, Has anyone ever had experiance with a Vision Master 150 ?, we have 2 onsite and I am trying to get accurate BGA paste height measurements from this machine, but both the machines are giving me results with huge variations, like +/- 0.2 thou

Many Thanks to You all. I think we should be ok with the majorty of our cap's if we set the comp. thicknes to 0.2 mm less than the actual size to be able to compensate for the variable thicknes from different wendors for a certain component. Do You

Good morning, The critical points for successful PIP technology are: 1. Gap between THT lead and PHT hole. It shouldn�t be greater that 0.2mm; 2. Lead shape. THT leads MUST be straight or you�ll get excessive voiding otherwise; 3. As Russ said, pas

Ah, I almost forget (forgot?) to mention that according to the Gerber files (which is the info we send to the PCB-house) the PCB land pattern for this LGA-36 0.35mm rounded pads and the boardhouse cannot achieve this. I understand them; 0.35mm pads,

Dear, Flexkhushi Do you mean 2 mm thick board or .2 mm board. If you are talking .2mm then you are refering to a flex circuit correct? What equipment will you be using to place the 01005 component? I

Are you absolutely sure the problem is with the humidity? We had a problem with 3528 size leds, damaged by the pick and place nozzle because a 0.2mm mistake in the height measurement. Also, we found that several suppliers are using fake desiccant ba

Hello, i don't know if is possible to dispense paste but for reduction of cost we use a diferent type of stencils, from aluminium of 0,2 mm, purchased from a typography of newspapers. Ofcourse the pcb for what we use this stencil are simple. But th

I'm investigating heat transfer by 1st order approximation between PCB and ambient air via encapsulate material (epoxy or gel or silicone), they have thermal conductivity of 0.2W/C but it hard to find specific heat capacity and density. Has anyone

thank you for reply here is picture of the board https://imgur.com/a/i2MfFBw on the bottom are pins/components which height is about 3-4 mm from bottom of the board we had to increase distance of board from nozzle to make clearance and we increas
