the way to calculate pcb assembly value, many digital producers will search for quotation from processing producers earlier than outsourcing the processing services. in reality, they'll nevertheless have numerous doubts approximately the very last quotations, so we are going to conduct a comprehensive price evaluation of pcb assembly.
first, required cloth costs before meeting
consistent with the consumer’s bom list, the shopping department of the processing company will make an inquiry, along with pcb naked board, digital components, and many others. now and again, assembly fees and engineering fees can be covered in purchasing citation. it wishes to cowl about five% of the fabric loss when purchasing the additives, because of the motive of cloth loss, like resistance and capacitance disk loading cloth and smt chip. for the small batch of pcba, engineering costs are normally covered in citation, such as the fees of processing document, stencil, converting smt line and so forth.
then, solder joint counting
pcb meeting fees encompass smt and dip after welding, and many others. that is accounted one after the other in line with the particular of circuit board solder joints and the method methods. commonly, a solder pad is counted as 1 point and solder joints of ic accounted by way of the range of ft. above 1206 smd precision of solder pad is counted in accordance with a solder pad to 2 factors, besides cd54 inductance counting to twelve points, other large inductance counted as 24 factors. further, plug spacing with 3.ninety six of one solder pad as 2 solder points. after counting all solder joints, its fees are counted amongst zero.008~zero.03 cny on the basis of solder joints.
for the small batch of pcba, engineering prices are commonly protected in quotation, consisting of the costs of processing record, stencil, converting smt line etc. pcba test charges also need to rely in line with each pcba board take a look at time; in terms of packaging logistics, special packaging materials in addition to the want to remember the fee of 3-proofing paint, further, in step with clients transaction phrases together with fob, it needs greater counting of customs logistics costs.
with a purpose to facilitate customers to fast calculate the price, we launched the online pricing system www.pcbastore.com. on the identical time, we offer one-stop components sourcing provider what’s a greater convenient choice for our clients. please feel loose to touch us thru svc@pcbastore.com or your income rep in pcbastore.com.
