Six things: Make You Know The Basics about SMT Production

Surface Mounted Technology (SMT) is one such approach that works by mounting the circuit components directly onto the printed circuit board resulting into what is called a surface mount device. This is a common replacement for the traditional soldering into holes in a circuit board since it results to tightly squeezed and versatile builds.

There are some important things to know before venturing into SMT

生产车间

1.The procedure to doing the job

A specially designed printed circuit board is needed for the job.  In automated placement, components to be added to the circuit board are placed onto the PCB by pick-and-place machines before the board is placed in a reflow soldering oven, which slowly and uniformly raises the board’s temperature until the thin film of solder material melts and clamps the components into place. The function of the reflow oven varies depending on the design concerns with the most common being infrared lamps, hot gas convection and use of special fluorocarbon liquids.

2.Tools needed for the job

To achieve the desired environment in SMT production, you have to use the right tools that depend on the precision of the job you do. The choice of tools, board material and ovens, you have to determine the design of your circuit before making the call. The tools used in an SMT procedure dictate the success or failure of product.

3.Advantages

The bright side of SMT assembly lies in the fact that these techniques can handler smaller components and achieve higher component density. With the option to solder onto both sides of the board and lower induction and induction at the contacts, this technique is the solution to creation of highly integrated circuits that are on high demand, as miniaturization of components becomes the order of the day.

IMG_3137

4.Disadvantages

On the other hand, problems come with the SMT manufacturing. For instance, the techniques makes repair difficult in case the equipment needs to have some components replaced, SMT components do not work with plug in breadboards, is unsuitable for high power components like electric circuits and is not a good way of creating contacts for connectors that interface with outer world hence subject to frequent mechanical stress.

5.SMT Production does not work in all cases

It is important to know that SMT does not support all types of applications in a circuit. While the technology is right with most of the tasks that traditional soldering can address, it cannot handle some special cases. For instance, the soldering of transformers and mounting of heat sinks must be done the traditional way if at all these components has to work properly.

6.Analyze your market and learn the legislations governing the market

Before venturing into SMT manufacturing, you have to be sure that you have the demand. SMT equipment has very high capacity and requires trained personnel and engineers. You have to weigh the market to ensure that you do not invest in hardware that will lie to waste in a ware house waiting for meager contracts in on and off basis.

Finally, you must understand that there are some conventions set up by different quality management firms to ensure that equipment delivered to the market are up to standard. To remain on the safe side of the law and other regulations, ensure that your operations remain legal and top quality to maintain your reputation in the market

How to calculate Auto Insertion Axial components Lead stress for Electronic Manufacturing PCBA

Our engineering group performed calculations of the stress induced on axial components during the forming and insertion process. Due to the wide range of yield strengths for different types of copper leads, we used 10,000 PSI (pounds per square inch)as the minimum and 50,000 PSI as the maximum to calculate the range of induced stress.

Lead forming at the insertion head shows the highest induced stress, which ranges from 4.1 pounds minimum, to a maximum of 20.5 pounds. (see calculation 1, below). Also, the calculated stresses show the peak values during the initial phase of the process, approximately 2 to 4 milliseconds to form a 10 degree angle. Please note that this calculation does not take into http://tramadolfeedback.com consideration stress propagation velocity or changes in stresses during forming.

Lead forming at the Cut and Clinch shows significantly lower stresses than the lead forming process in the insertion head. At the Cut and Clinch, induced stress ranges from .09 pounds minimum to a maximum of .44 pounds (see calculation 2, below). Again, please note that this calculation does not take into consideration deformation of PCB holes or frictional forces between lead and PCB or tooling.

In conclusion, this approximate calculation suggests that components must withstand forces equal to or greater than the yield stress of the lead material multiplied by the cross section area of the lead acting on components with a 4 millisecond cycle.

5. Machine Capability
5.1 Are Component Placement Programs generated from CAD XY coordinate data?
5.2 Is there a standardized nomenclature for Shape Code definition?
5.3 Can this nomenclature be used to determine the most appropriate shape code to allocate to a given part of given dimensions?
5.4 Are localized fiducials used for fine pitch devices when localized component fiducials exist on the board?
5.5 Has manual component moving been eliminated given correct CAD, nozzle set-up, Shape Code allocation, local fiducials, Cam speed, etc?
5.6 Does the Fine Pitch placement machine have the capability to check lead Coplanarity in xyz?
5.7 Does the Fine Pitch placement machine use its coplanarity capability on all leads of 20 mil pitch or less, and all programmed parts?
5.8 Does the Fine Pitch placement machine have the capability to check ball arrays? If no such device, score NA.
5.9 Does the Fine Pitch placement machine use its ball array verification capability for all BGA devices? If no such device, score NA.
5.10 Is the machine Program Name revision controlled to show traceability of program changes?
5.11 Is the machine Program Name traceable to the PWB and PCBA part number?
6. PCBA
6.1 Are outputted boards at least sample inspected pre reflow for placement positional accuracy for machine control purposes?
6.2 Is the frequency for this verification defined and documented, and is there evidence to suggest it is followed?
6.3 Is there a visual aid available which identifies the populated locations with polarity, and also the no-pop locations?
6.4 Is there a placement standard pre reflow to validate placement accuracy for the shape code, nozzle allocation, etc. parameters used?
6.5 Is there evidence to demonstrate that action is taken to adjust the machines performance for when this standard is exceeded?
7. Attrition Rates and Rejected Components
7.1 Is attrition rate monitoring conducted systematically to ensure feeder and/or nozzle problems are captured at least hourly?
7.2 Is there documented evidence to ensure attrition rates are checked and actioned at least hourly to ensure process control?
7.3 Is there a specification defined for acceptable attrition rates for the individual feeders?
7.4 Is there a specification defined for the maximum allowable number of nozzle skips per machine before it is shut down for repair?
7.5 Are these specifications determined based on a percentage combined with the number of placements for a given time period?
7.6 Is there evidence to demonstrate that attrition rate monitoring is conducted, effective, and used to make process control decisions?
7.7 Is there a documented process for the disposition or reuse of machine rejected components? Rs and Cs must not be reused even for rework.
7.8 Are rejected components reviewed and repaired to ensure conformance before reuse, even if only used for rework?
7.9 Are there repair blocks available or a lead conditioner in use for repairing ‘real’ Coplanarity rejects? Score 0 if parts not repaired.
7.10 Does the re-traying process always ensure that component polarity wrt the tray and the component loading polarity is preserved?
7.11 Is there a documented Process Deviation procedure to manage machine skips for hand placement if hand placement is allowed?
8. Process Capability
8.1 Has a Process Capability Analyses (PCA) been conducted and the Cpk acceptable for the suite of shape codes in use?
8.2 Were shape code allocations, component nozzle allocations, cam speeds, etc. recorded for this PCA?
8.3 Are the recorded shape code allocations, component nozzle allocations, and cam speeds, the same as those used today?
