It looks like the Zelprint LT300 is LPKF too... The first one was an LPKF Protoprint S, and the second was an LPKF Zelprint LT300. Are there any of these printers that have a device to actually apply the solder paste with consistent and constant pre

We have had a 300 for about three years. The mechanicals are pretty solid, but the software has much to be desired in my opinion. It is not intuitive.You have to drill into several layers and navigate all over the place to make simple changes. Mecha

Which compact oven manufacturer makes a better product? Essemtec or DDM? The Essemtec units look the same as Manncorp. I have found 2 RO300FC's and a Novastar 1800. The 1800 looks like it hits a higher temperature but not sure if its needed to go

Hello, Standard way to calculate stencil design can be done as follows: A normal ratio of aperture width/stencil thickness = 1.5 for pitches below 650u A normal ratio of stencil aperture width against pad width = 0.8-0.9 (or stencil aperture 10%-20

| | Hi, | | I just cheesed my previous attempt at this. I looked through IPC 600 and couldn't find anything relating to dimensional stability of a board with regard to stretch. I found bow and twist but nothing on size. I have a PCB that is .030"

The 300 degrees is the temperature as measured at the sensor. The actual air temperature just above your PCB may actually be much less. If the oven is properly calibrated then the 300 should represent air temperature at the board but I have seen ma

Currently use Hysol TS300 latex mask and need to explore alternative methods of drying the mask. The mask is applied with a Asymtek Century Dispenser and placed on drying shelves. Air dry is dependent on temperature/humidity. Tried all the UV masks o

I would like to have some advise or explaination about the IPC610 spec. Page 6-51 and 6-52 concerning the solder stains on gold finguers: On the page 6-51, it's recommended to inspect the gold finguers with the unaided eye, but on the page 6-52, th

The CyberOptics LSM 300 cannot provide true 3D volumetric measurements. It is impossible to measure volume using a "Box" that is drawn around a feature without the same characteristics. Owners of the LSM 300 try it for yourself. Move the stripe ar
