Tools of the trade / Re: High speed Pick & Place for $3600
You only need to put a line for head one and two interleaving so the machine picks one then head two and places both.

Hi Alan,

Do you know if Hothotsmt are the manufacturer or a reseller, just wondering why the SMT50 is considerably cheaper on Taobeo.com?
If you buy on Taobao the complete risk is on your side. You need to do the communication to fix the specification and send the money using wire transfer to the factory. No Paypal payment to secure. And maybe the machine price is not for the fully equipped machine.

When you replaced the stepper controllers did you just replace the controllers for the x axis and y axis or did you replace all of them? Are the stepper motors Nema17 or Nema23? Do you know which model of Leadshine DSP controllers that you fitted?
I used the DM556 controller for X,Y,drag motor west, drag motor north.

Lots of different sellers have the TM220A/240A models but very few seem to sell the SMT50
The manufacturer is a small company not like TM220/240A factory

The shipment costs to Europe are about 700USD don't forget to add. (Hothotsmt price is included)

With the SMT50 model they show pictures of the machine with an extra feeder bank on the back, but it isn't supplied with this as standard. Did you go for this option?
Yes I ordered the machine fully equipped

Quote
Does this use the same method of feeding by using a pin on the nozzle head assembly?
Yes the same drag feeder as on the left side

Quote
Any idea how much this rear feeder bank option costs and if it works ok?
I don't know the price difference you can ask sunny

It works the same way like the left feeder bank but have different line sizes.
The left bank has 20 x 8mm lines.
Don't forget to order a tray for TQFP chips they made it from aluminium and it will cost about 120$.

Does it use a downward camera or laser for fudicial alignment and is this tricky to set up?
A down looking camera is used for fiducial recognition. It took some time to adjust the light but it works good.
You only need to add 2 positions on your board and check it using teach in function.
Finally a switch in the project options enables this function.

How does the peel off tape mechanism work on the SMT50
The tape is pulled by a roller which is driven for and back to release the tape on drag movement and pull it back after.
You don't need a spool the tape moves trough this mechanics.

Quote
It looks like it also needs a compressed air supply?
Yes a small airbrush compressor will do the job the vacuum is generated inside using venturi nozzle.
The noise level is ok.

But you need to change the stepper driver they produce the loudest noise if the machine is in standby and moving.

Can you tell me what is the difference is between the TP01 and the SMT50 models?

The TP01 is a small cheap machine for hobbyist who want a machine using vision and mechanical alignment.
They use a special software running on windows build for this machine.
If you like to spent less money but want to have vision alignment and spend some time to adjust the machine this is the right choice.

I think the SMT50 is more professional it is more stable than TM240A and more precise than TP01.
But the motor drivers are noisy the complete machine needs adjustment for every position because there is no factory setup done.
It has 35 feeder lines and the option to put trays or custom feeder in the working area to pickup TQFP parts.
You can define the position and count in the software.
But the feeder handling is more complicted than TM240A feeder.

Quote
Do either of these have removable feeder
I don't know a machine below 10000$ supporting removeable feeders except my SMT700.

Quote
BTW Are you still on target with releasing your SMT700 before the end of this year?
I hope so we have some problems to find a good manufacturer in China.
If we do the production in Europe the price will rise up to 10000€.
There is a lot of work to do but I hope to build the best machine in this price range.

How good is the English version of the win xp software? Is it usable?

The english software is usefull you can improve the translation by yourself because it use a translation file.
I have done my own translation for my new SMT700 machine which uses the same software.

It is possible to support more languages if you create more language files.

Quote
Is this machine much slower than the 240A when not using the camera and can you select to use the camera only for certain components?
The SMT50 is much slower when you use the camera because the adjustment process needs some time maybe 2s for each part.
One reason is the placement head has more weight but the machine runs much smoother without vibrations so you can place at the same speed more accurate.
You can choose for each component if you like to use the camera and which alignment procedure should be done.
Over all the SMT50 is faster because you don't need to realign the components.
I improved my SMT50 now using leadshine DSP stepper driver. Now the movement is smoother and there is no noise in standby.
I don't like the peel off mechanics and the reel handling on this machine.
My SMT700 improves this and you can change feeder blocks.

Quote
Does the "pin on head assembly" method of feeding the tapes work ok?
Yes it woorks good but you need to adjust each feeder line by yourself.
The advantage is the software support different feeder types so it is possible to pick up from trays or strips.

Quote
Does the camera work ok with the software?
Yes the camera works ok but I had some problems at the beginning my fiducial recognition won't work.
I improved the light and got a new software to get it up and running.
The SMT700 uses better cameras and a different illumination.

Quote
I see that you are also developing the SMT700 machine featured in another thread here (which looks brilliant BTW), is this machine part of your project?
Thank you for the compliments.
Yes I checked different machines on the market and use the SMT50 and TM240A for production.

By the way I want to sell me TM240A and the TP01 machine in Germany.
If anyone is interested please send me a mail.

Hi maddoc,

we are on the timeline the machine will be ready end of the year.
Currently we are testing some of our new constructions to finish the machine prototype end of summer.
We need to check the design of the clutches.
The base construction is finished I need to draw the parts mounted in the base compartment of the SMT700.

Regards
Michael

Hi Sam,
The product will be shipped from Shanghai or maybe Germany.
This is a precision printer for prototype boards up to 300x200mm print area.
It need’s not so much space like the big  A3 sized printer.
You can fix prototype stencils at different sizes.
Which size do you need we plan a second size too.
I hope we begin the shipping end of August.
Best regards
Michael

SMALLSMT Stencil printer STP300

The design is finished we plan to resell the printer for 499USD.
We can print up to 200x300mm size.
You can adjust the workplate in X and Y direction for +/- 5mm.
Theta adjustment is in the Range of +/- 2°.
The initial board placement is done by moving the magnetic fixtures on the workplate.
It is possible to use varios stencil sizes by adjusting the stencil holder.



Here are the final pictures
