Mandritra ny dingana PCB famolavolana, raha mety hisy ny loza mety hitranga mialoha ary hialana mialoha, hihatsara ny tahan’ny fahombiazan’ny famolavolana PCB. Orinasa maro no manombatombana ny tetikasa miaraka amin’ny mari-pahaizana momba ny taham-pahombiazan’ny tabilao famolavolana PCB.

Ny lakilen’ny fanatsarana ny taham-pahombiazan’ny tabilao dia ny famolavolana ny fahamendrehana famantarana. Ao amin’ny famolavolana rafitra elektronika ankehitriny, be dia be ny drafitry ny vokatra, vitan’ny mpanamboatra puce, ao anatin’izany ny chip ampiasaina, ny fomba fananganana ny peripheral circuit sns. Amin’ny ankabeazan’ny fotoana, ny injenieran’ireo fitaovana dia tsy mila mieritreritra ny olan’ny fitsipiky ny fizaran-tany fa mila manao PCB azy manokana fotsiny.

Na eo aza izany, ao anatin’ny dingan’ny famolavolana PCB no ahitan’ny orinasa maro fahasahiranana, na ny endrika PCB tsy milamina, na tsy mandeha. Ho an’ny orinasa lehibe, mpanamboatra chip maro no hanome fanampiana ara-teknika sy fitarihana amin’ny famolavolana PCB. Saingy ny orinasa kely sy salantsalany sasany dia sahirana mahazo izany fanohanana izany. Noho izany, tsy maintsy mitady fomba hanaovanao ny tenanao ianao, izay mitarika olana maro, izay mety mitaky fanontana maro sy fanaovana deboka lava. Raha ny marina, raha azonao ny fomba famolavolana ny rafitra dia azo sorohina izany. Here are three tips for reducing PCB design risk.

1, the system planning stage is best to consider the problem of signal integrity, the whole system is built like this, the signal from one PCB to another PCB can receive correctly? Ity dia mila tombana amin’ny dingana voalohany, ary tsy sarotra ny manombatombana ny olana. Fahalalana kely momba ny fahamendrehana famantarana sy ny fikirakirana rindrambaiko tsotra vitsivitsy no mahavita azy.

Second, in the PCB design process, the use of simulation software to evaluate the specific wiring, observe whether the signal quality can meet the requirements, the simulation process itself is very simple, the key is to understand the principle of signal integrity knowledge, and used for guidance.

Third, in the process of PCB, we must carry out risk control. Betsaka ny olana, ny rindrambaiko fanahafana dia tsy misy fomba hamahana, tsy maintsy fehezin’ny mpamolavola. Ny lakilen’ity dingana ity dia ny fahafantarana izay misy ny risika sy izay tokony hatao hisorohana azy ireo, miaraka amin’ny fahalalana ny tsy fivadihana famantarana.

Raha azo raisina tsara amin’ny fomba famolavolana PCB ireo teboka telo ireo, dia hihena be ny risika famolavolana PCB, ho kely kokoa ny mety hisian’ny lesoka aorian’ny averina miverina ny tabilao, ary ho mora ihany ny debugging.
