Hi, I see it's easier to use a few profiles. Simply and easy! But my advice is to make own profile for each board.The thickness is ok but there are other characteristics you miss that way. Even board material is not the same. If someone tells you t

FUJI DUDE- You can purchase a Kit from IPC for verifying machine acceptability. IPC-9850 full kit with Components and boards, and such will set you back around $26,250 (member price). Just the glass board alone will cost you $3,800 (member Price).Thi

Do some push / pull testing. Typically with black pad, you can flick the components right off the board. If you have this, the boards are about as reliable as a Yugo. If you get decent push / pull results, odds are you don't have black pad and you

Kev, I looked up records of various hollis machines with 3 preheat zones. and with progressive preheat temp. of 300 400 and 500 with a speed of 3.5ft/min the topside board temp was 120C before entering the wave. the preheat elements were infrared. W

What affect does moisture have on sensitive components on a board as it waits for thru-hole assembly? Suppose I run a batch of boards today and the assembly dept won't be able to get to it til maybe a month from now, is it okay to just let the boards

I got some information on this support mechanism but was a little unsure how it worked. Let's suppose you're getting ready to run the second side, do you place the board on this support and have the support travel into the printer? Or is the support

No one knows what type of board you use. So, assuming you're talking a fairly standard FR4. Q1a. actually, what is max temperature and duration can a bare PCB reflow without any quality problem? A1a. We'd guess your board could take 250*C for may

Hi All We have two boards that we produce which are chip on glue. For this we use KME BD12's which use air to dispense the glue dot on to the board. This is not ideal as the glue dot size differs as we go down the tube causing us quality problems.
