I know its not going to place it at exactly that spot every single time there will be some variance.

Smt machine tolerance. Smt surface mount technology component placement systems commonly called pick and place machines or pps are robotic machines which are used to place surface mount devices smds onto a printed circuit board pcb. Dfm and smt assembly guideline tb 2082 revision c 34 connector float allowance and pcb fabrication tolerances the nexlev connector is designed to accommodate smt assembly and pcb fabrication tolerances. Built upon the same architecture as manncorps popular mc series of smt pick and place machines the new mc 400 is specially designed for startups product development labs and contract manufacturers that need to build prototypes or short runs in house with high precision and quick turn around times. As one of the largest stocking distributors in the us for aim soldering products we provide all the materialssuch as solder paste wire flux and solder barused in your. The place function follows the solder paste function stencil printer. Hotbar soldering machine smt machine pulse heat bonding machine manufacturer supplier in china offering smt hot bar soldering machine welding equipment split type lead free solder pot desktop soldering pot lead free solder pot and so on. Robert voigt ddm novastar. Machine capability is measured in cm and cmk. Smt equipment assembly automation technology. How to select a pick and place machine. Below are the total allowances for the connector design and the recommended pcb fabrication tolerances. Mc 400 automatic pick and place. Total connector float allowance. Advanced precision distribution is your source for everyday consumable products used in the assembly of printed circuit boards and other common electronic assemblies. If i am trying to place a component at x 316 and y528 what is the tolerance that the machine will put it at that exact location.

Placement tolerances cm402 cm212 cm602 nov 26 2014 placement tolerances cm402 cm212 cm602 no guess i should have tried to explain it better. An electronic device so made is called a surface mount device smd. A pick and place machine is the second step in a paste place reflow assembly operation. It is a snapshot picture that shows how well a machine is performing right now in relation to the tolerance limits. Advanced precision distribution smt supplies. They are used for high speed high precision placing of broad range of electronic components like capacitors resistors integrated circuits onto the pcbs which are in turn. Innovative engineering concept with strong swiss made mechanical experienced know how with our modular concept we propose easy to use equipment and peripherical modules according to your own specifications. When measuring machine capability you must not alter machine settings or change tools materials operators or measurement methods stop the machine etc. Selecting a pick and place machine.
