Disastrous Consequences (solved: fog with Intrepid lensboard)

[Kiwi7475]

The camera is compatible with Sinar lens boards, which are very common. Critics have had their say. Why not leave it at that? If not, the end result will likely be another manufacturer who won't post here.

I tend to agree that we're beating a dead horse and this thread should now be closed by the moderators.

I really do appreciate everyones opinions on this but FR4 is a great choice for our lens boards I will explain why,

Aluminium boards = Cutting (water jet or laser) + Deburring + Tumbling or Linishing + Anodising + Laser engraving our logo + high shipping cost when done at our scale = surprisingly high cost of lens board

Wood boards = it's very hard to find 2mm thick wood that can be easily held down and cut. making the 100s of boards we need each month would be impracticle

FR4 = board arrives all ready duburred, finished in black and with logo on it as this is all part of standard pre existing product manufacturing process (PCBs) they are excellent quality light weight and work just as well as any other material we have used.

We used to make boards out of aluminium using the method above, it was a pain. I wouldn't even bother trying to make them out of wood. Work holding 2mm wood is nightmare inducing. I know lots of people on here have all sorts of experience in a range of fields but as someone who has had to make literally tens of thousands of lens boards over the last 6 years the FR4 process is miles better than anything else we have tried, and we have tried all sorts! maybe its not your cup of tea but they make for great lens boards and the whole production process is so simple we would never look back.

if you are still not sure then we will have to just agree to disagree

I completely agree with this and see no reason to avoid FR4 as being somehow risky or failure-prone. It's easy to throw words like that around until you're the one responsible for making a product to spec and to cost, and then suddenly words like 'deburring' and 'anodising' give you nightmares.
