Here are some questions you should be considering... How many of each machine type are actually installed and being used in the market? What is the local support in your area from each vendor? Where are their spare parts warehoused? What is the w

Stencils on average should be a low cost to you, compared to the other equipment you are buying. A couple hundred bucks (U.S.) is all you should be paying. Making a stencil is harder than you would think. Set-up a visit with a local shop while n

You could have said "why don't you just flop 'em over twice into the right tray?" lol. Yeah, that's the right way. I was kind of focused on what I had to do here to get two different parts from full trays into two cut-in-half-the-long-way trays sinc

I would love to see the documentation of the experiment that indicated that a 24-hour/70 degree C bakeiing cycle at 10Pa is more effetive than a 24-hour 125 deg C baking cycle at normal atmosphere. We have looked at the old Levey-Perlmann paper and f

Wow, Chunks, condescension becomes you. Not. I think that in this forum when someone mentions *stencil* printing and doesn't specify what material, we tend to gravitate towards a scenario that involves printing solder paste first, then adhesive. If

Operator, Think "opposite". You actually want to MINIMIZE the ramp-up rate. Think about 2 - 3�C per second as your upper limit for ramp up. You don't want to go more than 4�C per second for thermal shock reasons. All of this, of course, depends

Q1: Can Stainless steel be soldered? A1: Yes, stainless steel can be soldered. Q2: If yes, is our normal process adequate? A2: We know nothing about your normal process. Common flux used in routine soldering will not step-up to the requirements nece

Stainless steel can NOT be soldered with the solder that is used in electronics, be it Sn63 or SAC305. I have 1st hand experience in this. Solder will NOT wet to it no matter how much flux is applied, or what type of flux is applied. Again, I have

I solder LEDs everyday from 0402 sizes on up. I work for an optical company so every product I make has LEDs. Some products have hundreds of LEDs per circuit. The problem is that clear materials are not filled materials and thus don't have the adv
