Is there a limit to the time that most components can stay at temperatures around 130-200 deg c? if i slow the time, the first 4 zones will be at this temp for about 5 minutes in no lead process. i am concerned that some chips wont be rated at this t

Im trying to figure out how to go about making a circuit board for making a music box basicly i plug it in. Has two speakers and when you lift the lid it auto plays the music, when you close it.. it stops playing. Very simple. Can anyone help me des

Beyond the materials cost, one approach to estimating the cost of assembling a board is: 1 Direct cost * Determine the processes required to assemble the board * Separate parts on BOM according to process * Multiply number of parts in each process by

we want to estimate the price of assemblyng a > board that contain both SMD and THT component . > and also we have the BOM file of this board . > please help me There is 3part on the cost: 1. PCB cost 2.Assembly cost 3.components cost. If you w

You can assess these costs anyway that makes sense to you. These machinery costs are 'direct' to the product. You could call them manufacturing overhead or machine cost. It all depends on what makes sense. As an example, depending on the products you

I have a problem with a I-pulse M1. Monday morning i came back from vecation, and started up the machines. warmed them up, and then..... When i started the program, (normaly it starts with scaning the nozzles) the head moves to the first nozzle, and

Hi, for this kind of issues I will always go with the flux first. Are you using only one type of flux? Is it alcohol based or water based? Do you apply a good quantity? Second I will go with the wave shape and speed, and last will be the temperatur

We only use one type of flux for Lead Free. It is an alcohol based no clean flux. Is the wave shape and speed as large a factor in ive soldering as in traditional wave soldering? When you say "decrease the Z" do you mean the nozzel or solder heigh

The 2009M is a water based flux and requires more preheating compared to alcohol based fluxes. After checking real chunks advice you might check if you hear sizzling when the solder touches the board (indicator that the water is not eliminated by you

We have a 3/6 Nozzle We do have monitors. One of our pots is leaded, the other is lead free. Our average wave height is ussually around 50%. Also, do you have any or found any benefits to removing nozzels at the end of your shift. I recall you say
