This manual PnP machine was made by assembling ready made parts available online and doing the remaining work at home. Since we are a start-up and low on budge we thought this maybe a good enough since professional PnPs are way too expensive. Rest of the SMT assembly process we are using is professional (Ren Thang STP-450 and APS Novastar GF-B-HT-N). The machine can place 0.5mm parts with good accuracy if operator have good vision 😉 or you can simply use the microscopic camera. Sorry for quirky English 🙂
Specialist PCB assembly service presented by PCB producers
Greatest things about specialized PCB assembly
If you’re considering doing the PCB assembly in-house at a professional level you are shortly going to discover the first investment expenditure is really large. You will require at the very least: one pick and place equipment, one stencil printing machine and one reflow oven. You probably also want other similar hardware for inspection work and hand soldering gear. Additionally , you will need labourforce and expertise that can expand the investment cost a great deal. And finally when you observe there’s very little ROI from this form of financial commitment you will definitely rapidly make the decision to outsource the PCB assembly service. In many cases outsourcing the PCB assembly job to an third-party firm should be more cost effective.
Then there is the facet of quality; a company focused upon PCB assembly services will surely have the specialist knowledge and workers to provide superior quality. They will also put money into their development by always having the most advanced technology to make sure that the buyer gets all the advantages of the innovative assembly technologies. It’s likely that you will hit a equipment related limitation doing in-house assembly if you cannot up-grade the equipment on a regular basis, as an example ,, you might end-up in a predicament in which you simply cannot efficiently assembly the new BGA package for a completely new processor.
There’s also the facet of quality control. A reliable PCB assembly shop may also get a reliable tested quality control service that you could possibly benefit from by not having to do the quality control in-house. Certainly, you may need to do extra quality control step in-house but it’s good to know at least the pcb’s are all doing the job in the right way when they walk out of the assembly line.
Down sides of expert PCB assembly
One reason you wouldn’t want to use outsourcing for the assembly of your project is to look after intellectual property. For anybody who is focusing on some mystery project or the most recent idea that will revolutionize something, you may want to keep that as secret as possible so in such cases you might do the PCB assembly in-house.
There are also cases when the turnaround time of a prototype is crucial so you can not afford to wait one week for your PCB to come back from a expert assembly line. Well then it might make more sense to perform the assembly on-site.
Expenditure is additionally an important cause you might not want to go with a professional PCB assembly house, particularly for smaller businesses or lovers. Expenditures for PCB assembly services have lessened substantially in the last few years so this is less of an issue lately but still you’ll not see tons of people sending their one off hobby projects to a PCB assembly house.
